Economic Historian of Inequality
Some people claim that the takeoff at the very top reflects the emergence of a new class of “superstars”—entrepreneurs, entertainers, sports stars, authors, and the like—who have exploited new technologies, such as the Internet, to enlarge their earnings at the expense of others in their field. If this is true, high rates of inequality may reflect a harsh and unalterable reality: outsized spoils are going to go to Roger Federer, James Patterson, and the WhatsApp guys. Piketty rejects this account. The main factor, he insists, is that major companies are giving their top executives outlandish pay packages.
.. Piketty calls the tendency for inequality to rise during periods when the rate of return on capital is higher than the economy’s rate of growth “the central contradiction of capitalism.”
