Modern Monetary Inevitabilities

ALEXANDRIA, VIRGINIA – In a recent Project Syndicate commentary, James K. Galbraith of the University of Texas at Austin Modern Monetary Theory and corrects some misunderstandings about the relationships among MMT, federal deficits, and central-bank independence. But Galbraith does not explore what is perhaps the most important issue of all: the political conditions needed to implement MMT effectively.

MMT owes its newfound relevance to the fact that deflation, rather than inflation, is becoming central banks’ main concern. For a high-debt, high-deficit economy like the United States, deflation is an especially serious threat, because it delays consumption and increases debtor anxiety. Consumers forego major purchases on the assumption that future prices will be lower. Homeowners with mortgages cut back their spending when they see home prices falling and the equity in their homes declining. These cutbacks worry the Federal Reserve, because they add to deflationary pressures and could trigger deeper spending cuts, stock-market declines, and widespread deleveraging.

The Fed’s inability so far to reach its 2% target for annual inflation suggests that it lacks the means to overcome persistent disinflationary forces in the economy. These forces include increased US , which diminishes aggregate demand by weakening employee bargaining power and increasing income inequality; population aging; inadequate investment in infrastructure and climate-change abatement; and technology-driven labor displacement. Making matters worse, US political gridlock assures continued commitment to economically exhausted strategies such as tax cuts for the rich, at the expense of investment in education and other sources of long-term growth. These conditions cry out for significant changes in US government spending and tax policies.

MMT is seen as a way to accomplish the needed changes. It holds that a government can spend as much as it wants if it borrows in its own currency and its central bank can buy as much of the government’s debt as necessary – as long as doing so doesn’t generate unacceptably high inflation. Both tax-cut advocates and supporters of public investment find little not to like.

MMT has been roundly criticized by economists across the political spectrum, from Kenneth Rogoff and Lawrence H. Summers of Harvard University to Paul Krugman of the City University of New York. All contend that it is a political argument masquerading as economic theory. But Galbraith and Ray Dalio of Bridgewater Associates see MMT differently. Dalio argues that MMT is real and, more to the point, it is an inevitable policy step in historically recurring debt-cycle downturns.

In his book Principles for Navigating Big Debt Crises, Dalio documents the steps that central banks have historically taken when faced with a booming economy that suddenly crumples under the weight of debt. The first step (Monetary Policy 1, or MP1) is

  1. to cut overnight official rates to stimulate credit and investment expansion. The second (MP2)
  2. is to buy government debt (quantitative easing) to support asset prices and prevent uncontrollable waves of deleveraging. If MP1 and MP2 are insufficient to halt a downturn, central banks take step three (MMT, which Dalio calls MP3) and
  3. proceed to finance the spending priorities that political leaders deem most essential. The priorities can range from financing major national projects to “helicopter money” transfers directly to consumers.

Achieving political agreement on what to finance and how is essential for implementing MP3 effectively. In a financial meltdown or other national emergency, political unity and prompt action are essential. Unity requires a strong consensus on what should be financed. Speed requires the existence of a trusted institution to direct the spending.

In the early 1940s, when the US entered World War II and winning the war became the government’s top priority, the Fed entered full MP3 mode. It not only set short- and long-term rates for Treasury bonds, but also bought as much government debt as necessary to finance the war effort. MP3 was possible because the war united the country politically and gave the Roosevelt administration near-authoritarian rule over the economy.

The core weakness of MP3/MMT advocacy is the absence of an explanation of how to achieve political unity on what to finance and how. This absence is inexcusable. Total US debt (as a share of GDP) is approaching levels associated with past financial meltdowns, and that doesn’t even account for the  associated with infrastructure maintenance, rising sea levels, and unfunded pensions. For the reasons Dalio lays out, a US debt crisis requiring some form of MP3 is all but inevitable.

The crucial question that any effort to achieve political unity must answer is what constitutes justifiable spending. Alexander Hamilton, America’s first Secretary of the Treasury, offered an answer in 1781: “A national debt,” he wrote, “if it is not excessive will be to us a national blessing.” A government’s debt is “excessive” if it cannot be repaid because its proceeds were spent in ways that did not increase national wealth enough to do so. Debt resulting from tax cuts that are spent on mega-yachts would almost certainly be excessive; debt incurred to improve educational outcomes, maintain essential infrastructure, or address climate change would probably not be. Accordingly, it will be easier to achieve political unity if MP3 proceeds are spent on priorities such as education, infrastructure, or climate.

The political test for justifying MP3-financed government spending, is clear: Will future generations judge that the borrowing was not “excessive”? Most Americans born well after WWII would say that the debt incurred to win that war was justified, as was the debt that financed the construction of the Interstate Highway System, which literally paved the way for stronger growth.

As the 1930s and 1940s show, MP3 is a natural component of government responses to major debt downturns and the political crises they trigger. We know much more about what contributes to economic growth and sustainability than we did in the first half of the twentieth century. To speed recovery from the next downturn, we need to identify now the types of spending that will contribute most to sustainable recovery and that in hindsight will be viewed as most justified by future Americans. We need also to design the institutions that will direct the spending. These are the keys to building the political unity that MMT requires. To know what to finance and how, future Americans can show us the way; we need only put ourselves in their shoes.

After Neoliberalism

For the past 40 years, the United States and other advanced economies have been pursuing a free-market agenda of low taxes, deregulation, and cuts to social programs. There can no longer be any doubt that this approach has failed spectacularly; the only question is what will – and should – come next.

The neoliberal experiment – lower taxes on the rich, deregulation of labor and product markets, financialization, and globalization – has been a spectacular failure. Growth is lower than it was in the quarter-century after World War II, and most of it has accrued to the very top of the income scale. After decades of stagnant or even falling incomes for those below them, neoliberalism must be pronounced dead and buried.
Vying to succeed it are at least three major political alternatives:
  1. far-right nationalism,
  2. center-left reformism, and the
  3. progressive left (with the center-right representing the neoliberal failure).

And yet, with the exception of the progressive left, these alternatives remain beholden to some form of the ideology that has (or should have) expired.

The center-left, for example, represents neoliberalism with a human face. Its goal is to bring the policies of former US President Bill Clinton and former British Prime Minister Tony Blair into the twenty-first century, making only slight revisions to the prevailing modes of financialization and globalization. Meanwhile, the nationalist right disowns globalization, blaming migrants and foreigners for all of today’s problems. Yet as Donald Trump’s presidency has shown, it is no less committed – at least in its American variant – to tax cuts for the rich, deregulation, and shrinking or eliminating social programs.

By contrast, the third camp advocates what I call , which prescribes a radically different economic agenda, based on four priorities. The first is to

  1. restore the balance between markets, the state, and civil society. Slow economic growth, rising inequality, financial instability, and environmental degradation are problems born of the market, and thus cannot and will not be overcome by the market on its own. Governments have a duty to limit and shape markets through environmental, health, occupational-safety, and other types of regulation. It is also the government’s job to do what the market cannot or will not do, like actively investing in basic research, technology, education, and the health of its constituents.
  2. The second priority is to recognize that the “wealth of nations” is the result of  – learning about the world around us – and social organization that allows large groups of people to work together for the common good. Markets still have a crucial role to play in facilitating social cooperation, but they serve this purpose only if they are governed by the rule of law and subject to democratic checks. Otherwise, individuals can get rich by exploiting others, extracting wealth through rent-seeking rather than creating wealth through genuine ingenuity. Many of today’s wealthy took the exploitation route to get where they are. They have been well served by Trump’s policies, which have encouraged rent-seeking while destroying the underlying sources of wealth creation. Progressive capitalism seeks to do precisely the opposite.
  3. This brings us to the third priority: addressing the growing problem of concentrated . By exploiting information advantages, buying up potential competitors, and creating entry barriers, dominant firms are able to engage in large-scale rent-seeking to the detriment of everyone else. The rise in corporate market power, combined with the decline in workers’ bargaining power, goes a long way toward explaining why inequality is so high and growth so tepid. Unless government takes a more active role than neoliberalism prescribes, these problems will likely become much worse, owing to advances in robotization and artificial intelligence.
  4. The fourth key item on the progressive agenda is to sever the link between economic power and political influence. Economic power and political influence are mutually reinforcing and self-perpetuating, especially where, as in the US, wealthy individuals and corporations may spend without limit in elections. As the US moves ever closer to a fundamentally undemocratic system of “one dollar, one vote,” the system of checks and balances so necessary for democracy likely cannot hold: nothing will be able to constrain the power of the wealthy. This is not just a moral and political problem: economies with less inequality actually perform better. Progressive-capitalist reforms thus have to begin by curtailing the influence of money in politics and reducing wealth inequality.3

There is no magic bullet that can reverse the damage done by decades of neoliberalism. But a comprehensive agenda along the lines sketched above absolutely can. Much will depend on whether reformers are as resolute in combating problems like excessive market power and inequality as the private sector is in creating them.

A comprehensive agenda must focus on education, research, and the other true sources of wealth. It must protect the environment and fight climate change with the same vigilance as the Green New Dealers in the US and Extinction Rebellion in the United Kingdom. And it must provide public programs to ensure that no citizen is denied the basic requisites of a decent life. These include economic security, access to work and a living wage, health care and adequate housing, a secure retirement, and a quality education for one’s children.

This agenda is eminently affordable; in fact, we cannot afford not to enact it. The alternatives offered by nationalists and neoliberals would guarantee more stagnation, inequality, environmental degradation, and political acrimony, potentially leading to outcomes we do not even want to imagine.

Progressive capitalism is not an oxymoron. Rather, it is the most viable and vibrant alternative to an ideology that has clearly failed. As such, it represents the best chance we have of escaping our current economic and political malaise.

It’s Time to Break Up Facebook (Chris Hughes)

Mark’s influence is staggering, far beyond that of anyone else in the private sector or in government. He controls three core communications platforms — Facebook, Instagram and WhatsApp — that billions of people use every day. Facebook’s board works more like an advisory committee than an overseer, because Mark controls around 60 percent of voting shares. Mark alone can decide how to configure Facebook’s algorithms to determine what people see in their News Feeds, what privacy settings they can use and even which messages get delivered. He sets the rules for how to distinguish violent and incendiary speech from the merely offensive, and he can choose to shut down a competitor by acquiring, blocking or copying it.

Mark is a good, kind person. But I’m angry that his focus on growth led him to sacrifice security and civility for clicks. I’m disappointed in myself and the early Facebook team for not thinking more about how the News Feed algorithm could change our culture, influence elections and empower nationalist leaders. And I’m worried that Mark has surrounded himself with a team that reinforces his beliefs instead of challenging them.

The government must hold Mark accountable. For too long, lawmakers have marveled at Facebook’s explosive growth and overlooked their responsibility to ensure that Americans are protected and markets are competitive. Any day now, the Federal Trade Commission is expected to impose a $5 billion fine on the company, but that is not enough; nor is Facebook’s offer to appoint some kind of privacy czar. After Mark’s congressional testimony last year, there should have been calls for him to truly reckon with his mistakes. Instead the legislators who questioned him were derided as too old and out of touch to understand how tech works. That’s the impression Mark wanted Americans to have, because it means little will change.

Facebook’s dominance is not an accident of history. The company’s strategy was to beat every competitor in plain view, and regulators and the government tacitly — and at times explicitly — approved. In one of the government’s few attempts to rein in the company, the F.T.C. in 2011 issued a consent decree that Facebook not share any private information beyond what users already agreed to. Facebook largely ignored the decree. Last month, the day after the company predicted in an earnings call that it would need to pay up to $5 billion as a penalty for its negligence — a slap on the wrist — Facebook’s shares surged 7 percent, adding $30 billion to its value, six times the size of the fine.

The F.T.C.’s biggest mistake was to allow Facebook to acquire Instagram and WhatsApp. In 2012, the newer platforms were nipping at Facebook’s heels because they had been built for the smartphone, where Facebook was still struggling to gain traction. Mark responded by buying them, and the F.T.C. approved.

Neither Instagram nor WhatsApp had any meaningful revenue, but both were incredibly popular. The Instagram acquisition guaranteed Facebook would preserve its dominance in photo networking, and WhatsApp gave it a new entry into mobile real-time messaging. Now, the founders of Instagram and WhatsApp have left the company after clashing with Mark over his management of their platforms. But their former properties remain Facebook’s, driving much of its recent growth.

.. When it hasn’t acquired its way to dominance, Facebook has used its monopoly position to shut out competing companies or has copied their technology.

The News Feed algorithm reportedlprioritized videos created through Facebook over videos from competitors, like YouTube and Vimeo. In 2012, Twitter introduced a video network called Vine that featured six-second videos. That same day, Facebook blocked Vine from hosting a tool that let its users search for their Facebook friends while on the new network. The decision hobbled Vine, which shut down four years later.

Snapchat posed a different threat. Snapchat’s Stories and impermanent messaging options made it an attractive alternative to Facebook and Instagram. And unlike Vine, Snapchat wasn’t interfacing with the Facebook ecosystem; there was no obvious way to handicap the company or shut it out. So Facebook simply copied it.

Facebook’s version of Snapchat’s stories and disappearing messages proved wildly successful, at Snapchat’s expense. At an all-hands meeting in 2016, Mark told Facebook employees not to let their pride get in the way of giving users what they want. According to Wired magazine, “Zuckerberg’s message became an informal slogan at Facebook: ‘Don’t be too proud to copy.’”

(There is little regulators can do about this tactic: Snapchat patented its “ephemeral message galleries,” but copyright law does not extend to the abstract concept itself.)

As a result of all this, would-be competitors can’t raise the money to take on Facebook. Investors realize that if a company gets traction, Facebook will copy its innovations, shut it down or acquire it for a relatively modest sum. So despite an extended economic expansion, increasing interest in high-tech start-ups, an explosion of venture capital and growing public distaste for Facebook, no major social networking company has been founded since the fall of 2011.

As markets become more concentrated, the number of new start-up businesses declines. This holds true in other high-tech areas dominated by single companies, like search (controlled by Google) and e-commerce (taken over by Amazon). Meanwhile, there has been plenty of innovation in areas where there is no monopolistic domination, such as in workplace productivity (Slack, Trello, Asana), urban transportation (Lyft, Uber, Lime, Bird) and cryptocurrency exchanges (Ripple, Coinbase, Circle).

I don’t blame Mark for his quest for domination. He has demonstrated nothing more nefarious than the virtuous hustle of a talented entrepreneur. Yet he has created a leviathan that crowds out entrepreneurship and restricts consumer choice. It’s on our government to ensure that we never lose the magic of the invisiblehand. How did we allow this to happen?

Since the 1970s, courts have become increasingly hesitant to break up companies or block mergers unless consumers are paying inflated prices that would be lower in a competitive market. But a narrow reliance on whether or not consumers have experienced price gouging fails to take into account the full cost of market domination. It doesn’t recognize that we also want markets to be competitive to encourage innovation and to hold power in check. And it is out of step with the history of antitrust law. Two of the last major antitrust suits, against AT&T and IBM in the 1980s, were grounded in the argument that they had used their size to stifle innovation and crush competition.

As the Columbia law professor Tim Wu writes, “It is a disservice to the laws and their intent to retain such a laserlike focus on price effects as the measure of all that antitrust was meant to do.

Facebook is the perfect case on which to reverse course, precisely because Facebook makes its money from targeted advertising, meaning users do not pay to use the service. But it is not actually free, and it certainly isn’t harmless.

Facebook’s business model is built on capturing as much of our attention as possible to encourage people to create and share more information about who they are and who they want to be. We pay for Facebook with our data and our attention, and by either measure it doesn’t come cheap.

I was on the original News Feed team (my name is on the patent), and that product now gets billions of hours of attention and pulls in unknowable amounts of data each year. The average Facebook user spends an hour a day on the platform; Instagram users spend 53 minutes a day scrolling through pictures and videos. They create immense amounts of data — not just likes and dislikes, but how many seconds they watch a particular video — that Facebook uses to refine its targeted advertising. Facebook also collects data from partner companies and apps, without most users knowing about it, according to testing by The Wall Street Journal.

Some days, lying on the floor next to my 1-year-old son as he plays with his dinosaurs, I catch myself scrolling through Instagram, waiting to see if the next image will be more beautiful than the last. What am I doing? I know it’s not good for me, or for my son, and yet I do it anyway.

The choice is mine, but it doesn’t feel like a choice. Facebook seeps into every corner of our lives to capture as much of our attention and data as possible and, without any alternative, we make the trade.

The vibrant marketplace that once drove Facebook and other social media companies to compete to come up with better products has virtually disappeared. This means there’s less chance of start-ups developing healthier, less exploitative social media platforms. It also means less accountability on issues like privacy.

Just last month, Facebook seemingly tried to bury news that it had stored tens of millions of user passwords in plain text format, which thousands of Facebook employees could see. Competition alone wouldn’t necessarily spur privacy protection — regulation is required to ensure accountability — but Facebook’s lock on the market guarantees that users can’t protest by moving to alternative platforms.

The most problematic aspect of Facebook’s power is Mark’s unilateral control over speech. There is no precedent for his ability to monitor, organize and even censor the conversations of two billion people.

Facebook engineers write algorithms that select which users’ comments or experiences end up displayed in the News Feeds of friends and family. These rules are proprietary and so complex that many Facebook employees themselves don’t understand them.

In 2014, the rules favored curiosity-inducing “clickbait” headlines. In 2016, they enabled the spread of fringe political views and fake news, which made it easier for Russian actors to manipulate the American electorate. In January 2018, Mark announced that the algorithms would favor non-news content shared by friends and news from “trustworthy” sources, which his engineers interpreted — to the confusion of many — as a boost for anything in the category of “politics, crime, tragedy.”

Facebook has responded to many of the criticisms of how it manages speech by hiring thousands of contractors to enforce the rules that Mark and senior executives develop. After a few weeks of training, these contractors decide which videos count as hate speech or free speech, which images are erotic and which are simply artistic, and which live streams are too violent to be broadcast. (The Verge reported that some of these moderators, working through a vendor in Arizona, were paid $28,800 a year, got limited breaks and faced significant mental health risks.)

As if Facebook’s opaque algorithms weren’t enough, last year we learned that Facebook executives had permanently deleted their own messages from the platform, erasing them from the inboxes of recipients; the justification was corporate security concerns. When I look at my years of Facebook messages with Mark now, it’s just a long stream of my own light-blue comments, clearly written in response to words he had once sent me. (Facebook now offers a limited version of this feature to all users.)

The most extreme example of Facebook manipulating speech happened in Myanmar in late 2017Mark said in a Vox interview that he personally made the decision to delete the private messages of Facebook users who were encouraging genocide there. “I remember, one Saturday morning, I got a phone call,” he said, “and we detected that people were trying to spread sensational messages through — it was Facebook Messenger in this case — to each side of the conflict, basically telling the Muslims, ‘Hey, there’s about to be an uprising of the Buddhists, so make sure that you are armed and go to this place.’ And then the same thing on the other side.”

Mark made a call: “We stop those messages from going through.” Most people would agree with his decision, but it’s deeply troubling that he made it with no accountability to any independent authority or government. Facebook could, in theory, delete en masse the messages of Americans, too, if its leadership decided it didn’t like them.

Mark used to insist that Facebook was just a “social utility,” a neutral platform for people to communicate what they wished. Now he recognizes that Facebook is both a platform and a publisher and that it is inevitably making decisions about values. The company’s own lawyers have argued in court that Facebook is a publisher and thus entitled to First Amendment protection.

No one at Facebook headquarters is choosing what single news story everyone in America wakes up to, of course. But they do decide whether it will be an article from a reputable outlet or a clip from “The Daily Show,” a photo from a friend’s wedding or an incendiary call to kill others.

Mark knows that this is too much power and is pursuing a twofold strategy to mitigate it.

  1. He is pivoting Facebook’s focus toward encouraging more private, encrypted messaging that Facebook’s employees can’t see, let alone control.
  2. Second, he is hoping for friendly oversight from regulators and other industry executives.

Late last year, he proposed an independent commission to handle difficult content moderation decisions by social media platforms. It would afford an independent check, Mark argued, on Facebook’s decisions, and users could appeal to it if they disagreed. But its decisions would not have the force of law, since companies would voluntarily participate.

In an op-ed essay in The Washington Post in March, he wrote, “Lawmakers often tell me we have too much power over speech, and I agree.” And he went even further than before, calling for more government regulation — not just on speech, but also on privacy and interoperability, the ability of consumers to seamlessly leave one network and transfer their profiles, friend connections, photos and other data to another.

I don’t think these proposals were made in bad faith. But I do think they’re an attempt to head off the argument that regulators need to go further and break up the company. Facebook isn’t afraid of a few more rules. It’s afraid of an antitrust case and of the kind of accountability that real government oversight would bring.

We don’t expect calcified rules or voluntary commissions to work to regulate drug companies, health care companies, car manufacturers or credit card providers. Agencies oversee these industries to ensure that the private market works for the public good. In these cases, we all understand that government isn’t an external force meddling in an organic market; it’s what makes a dynamic and fair market possible in the first place. This should be just as true for social networking as it is for air travel or pharmaceuticals.

In the summer of 2006, Yahoo offered us $1 billion for Facebook. I desperately wanted Mark to say yes. Even my small slice of the company would have made me a millionaire several times over. For a 22-year-old scholarship kid from small-town North Carolina, that kind of money was unimaginable. I wasn’t alone — just about every other person at the company wanted the same.

It was taboo to talk about it openly, but I finally asked Mark when we had a moment alone, “How are you feeling about Yahoo?” I got a shrug and a one-line answer: “I just don’t know if I want to work for Terry Semel,” Yahoo’s chief executive.

Outside of a couple of gigs in college, Mark had never had a real boss and seemed entirely uninterested in the prospect. I didn’t like the idea much myself, but I would have traded having a boss for several million dollars any day of the week. Mark’s drive was infinitely stronger. Domination meant domination, and the hustle was just too delicious.

Mark may never have a boss, but he needs to have some check on his power. The American government needs to do two things: break up Facebook’s monopoly and regulate the company to make it more accountable to the American people.

First, Facebook should be separated into multiple companies. The F.T.C., in conjunction with the Justice Department, should enforce antitrust laws by undoing the Instagram and WhatsApp acquisitions and banning future acquisitions for several years. The F.T.C. should have blocked these mergers, but it’s not too late to act. There is precedent for correcting bad decisions — as recently as 2009, Whole Foods settled antitrust complaints by selling off the Wild Oats brand and stores that it had bought a few years earlier.

There is some evidence that we may be headed in this direction. Senator Elizabeth Warren has called for reversing the Facebook mergers, and in February, the F.T.C. announced the creation of a task force to monitor competition among tech companies and review previous mergers.

How would a breakup work? Facebook would have a brief period to spin off the Instagram and WhatsApp businesses, and the three would become distinct companies, most likely publicly traded. Facebook shareholders would initially hold stock in the new companies, although Mark and other executives would probably be required to divest their management shares.

Until recently, WhatsApp and Instagram were administered as independent platforms inside the parent company, so that should make the process easier. But time is of the essence: Facebook is working quickly to integrate the three, which would make it harder for the F.T.C. to split them up.

Some economists are skeptical that breaking up Facebook would spur that much competition, because Facebook, they say, is a “natural” monopoly. Natural monopolies have emerged in areas like water systems and the electrical grid, where the price of entering the business is very high — because you have to lay pipes or electrical lines — but it gets cheaper and cheaper to add each additional customer. In other words, the monopoly arises naturally from the circumstances of the business, rather than a company’s illegal maneuvering. In addition, defenders of natural monopolies often make the case that they benefit consumers because they are able to provide services more cheaply than anyone else.

Facebook is indeed more valuable when there are more people on it: There are more connections for a user to make and more content to be shared. But the cost of entering the social network business is not that high. And unlike with pipes and electricity, there is no good argument that the country benefits from having only one dominant social networking company.

But the cost of entering the social network business is not that high. And unlike with pipes and electricity, there is no good argument that the country benefits from having only one dominant social networking company.

Still others worry that the breakup of Facebook or other American tech companies could be a national security problem. Because advancements in artificial intelligence require immense amounts of data and computing power, only large companies like Facebook, Google and Amazon can afford these investments, they say. If American companies become smaller, the Chinese will outpace us.

While serious, these concerns do not justify inaction. Even after a breakup, Facebook would be a hugely profitable business with billions to invest in new technologies — and a more competitive market would only encourage those investments. If the Chinese did pull ahead, our government could invest in research and development and pursue tactical trade policy, just as it is doing today to hold China’s 5G technology at bay.

The cost of breaking up Facebook would be next to zero for the government, and lots of people stand to gain economically. A ban on short-term acquisitions would ensure that competitors, and the investors who take a bet on them, would have the space to flourish. Digital advertisers would suddenly have multiple companies vying for their dollars.

Even Facebook shareholders would probably benefit, as shareholders often do in the years after a company’s split. The value of the companies that made up Standard Oil doubled within a year of its being dismantled and had increased by fivefold a few years later. Ten years after the 1984 breakup of AT&T, the value of its successor companies had tripled.

But the biggest winners would be the American people. Imagine a competitive market in which they could choose among one network that

  • offered higher privacy standards, another that
  • cost a fee to join but had little advertising and another that would allow users to
  • customize and tweak their feeds as they saw fit.

No one knows exactly what Facebook’s competitors would offer to differentiate themselves. That’s exactly the point.

The Justice Department faced similar questions of social costs and benefits with AT&T in the 1950s. AT&T had a monopoly on phone services and telecommunications equipment. The government filed suit under antitrust laws, and the case ended with a consent decree that required AT&T to release its patents and refrain from expanding into the nascent computer industry. This resulted in an explosion of innovation, greatly increasing follow-on patents and leading to the development of the semiconductor and modern computing. We would most likely not have iPhones or laptops without the competitive markets that antitrust action ushered in.

Adam Smith was right: Competition spurs growth and innovation.

Just breaking up Facebook is not enough. We need a new agency, empowered by Congress to regulate tech companies. Its first mandate should be to protect privacy.

The Europeans have made headway on privacy with the General Data Protection Regulation, a law that guarantees users a minimal level of protectionA landmark privacy bill in the United States should specify exactly what control Americans have over their digital information, require clearer disclosure to users and provide enough flexibility to the agency to exercise effective oversight over time. The agency should also be charged with guaranteeing basic interoperability across platforms.

Finally, the agency should create guidelines for acceptable speech on social media. This idea may seem un-American — we would never stand for a government agency censoring speech. But we already have limits on

  • yelling “fire” in a crowded theater,
  • child pornography,
  • speech intended to provoke violence and false statements to manipulate stock prices.

We will have to create similar standards that tech companies can use. These standards should of course be subject to the review of the courts, just as any other limits on speech are. But there is no constitutional right to harass others or live-stream violence.

These are difficult challenges. I worry that government regulators will not be able to keep up with the pace of digital innovation. I worry that more competition in social networking might lead to a conservative Facebook and a liberal one, or that newer social networks might be less secure if government regulation is weak. But sticking with the status quo would be worse: If we don’t have public servants shaping these policies, corporations will.

Some people doubt that an effort to break up Facebook would win in the courts, given the hostility on the federal bench to antitrust action, or that this divided Congress would ever be able to muster enough consensus to create a regulatory agency for social media.

But even if breakup and regulation aren’t immediately successful, simply pushing for them will bring more oversight. The government’s case against Microsoft — that it illegally used its market power in operating systems to force its customers to use its web browser, Internet Explorer — ended in 2001 when George W. Bush’s administration abandoned its effort to break up the company. Yet that prosecution helped rein in Microsoft’s ambitions to dominate the early web.

Similarly, the Justice Department’s 1970s suit accusing IBM of illegally maintaining its monopoly on computer sales ended in a stalemate. But along the way, IBM changed many of its behaviors. It stopped bundling its hardware and software, chose an extremely open design for the operating system in its personal computers and did not exercise undue control over its suppliers. Professor Wu has written that this “policeman at the elbow” led IBM to steer clear “of anything close to anticompetitive conduct, for fear of adding to the case against it.”

We can expect the same from even an unsuccessful suit against Facebook.

Finally, an aggressive case against Facebook would persuade other behemoths like Google and Amazon to think twice about stifling competition in their own sectors, out of fear that they could be next. If the government were to use this moment to resurrect an effective competition standard that takes a broader view of the full cost of “free” products, it could affect a whole host of industries.

The alternative is bleak. If we do not take action, Facebook’s monopoly will become even more entrenched. With much of the world’s personal communications in hand, it can mine that data for patterns and trends, giving it an advantage over competitors for decades to come.

I take responsibility for not sounding the alarm earlier. Don Graham, a former Facebook board member, has accused those who criticize the company now as having “all the courage of the last man leaping on the pile at a football game.” The financial rewards I reaped from working at Facebook radically changed the trajectory of my life, and even after I cashed out, I watched in awe as the company grew. It took the 2016 election fallout and Cambridge Analytica to awaken me to the dangers of Facebook’s monopoly. But anyone suggesting that Facebook is akin to a pinned football player misrepresents its resilience and power.

An era of accountability for Facebook and other monopolies may be beginning. Collective anger is growing, and a new cohort of leaders has begun to emerge. On Capitol Hill, Representative David Cicilline has taken a special interest in checking the power of monopolies, and Senators Amy Klobuchar and Ted Cruz have joined Senator Warren in calling for more oversight. Economists like Jason Furman, a former chairman of the Council of Economic Advisers, are speaking out about monopolies, and a host of legal scholars like Lina Khan, Barry Lynn and Ganesh Sitaraman are plotting a way forward.

This movement of public servants, scholars and activists deserves our support. Mark Zuckerberg cannot fix Facebook, but our government can.
