Hitting a 3% target would result in an economy that’s nearly $13 trillion larger in 30 years.
But consider what happens to the CBO’s numbers assuming 3% annual growth. By 2040 the economy would expand not to $29.9 trillion, but to $38.3 trillion, according to an analysis by Research Affiliates, a California investment firm. That’s an additional output of $8.4 trillion—roughly the entire annual production today of every state west of the Mississippi River.
.. Many blue-chip economists agree with the CBO that a growth rate of about 2% is the best that America can achieve.
.. But the right policies can counter these trends. Productivity should surge with improvements in robotics, artificial intelligence and automation. Self-driving cars could cut transportation costs dramatically in coming years. Washington could facilitate this renaissance by giving companies an incentive to invest.
.. at least seven million Americans in their prime working years—18 to 65—would be on the job today if labor-force participation had not dropped since 2000. A strong economy, paired with welfare reforms, could draw millions back to work.
.. And immigration is America’s natural demographic safety valve.
