The book that’s reviving Marx for the 21st century

Daniel Shuchman:

Thomas Piketty likes capitalism because it efficiently allocates resources. But he does not like how it allocates income. There is, he thinks, a moral illegitimacy to virtually any accumulation of wealth, and it is a matter of justice that such inequality be eradicated in our economy. The way to do this is to eliminate high incomes and to reduce existing wealth through taxation.

“Capital in the Twenty-First Century” is Mr. Piketty’s dense exploration of the history of wages and wealth over the past three centuries. He presents a blizzard of data about income distribution in many countries, claiming to show that inequality has widened dramatically in recent decades and will soon get dangerously worse. Whether or not one is convinced by Mr. Piketty’s data—and there are reasons for skepticism, given the author’s own caveats and the fact that many early statistics are based on extremely limited samples of estate tax records and dubious extrapolation—is ultimately of little consequence. For this book is less a work of economic analysis than a bizarre ideological screed.

A professor at the Paris School of Economics, Mr. Piketty believes that only the productivity of low-wage workers can be measured objectively. He posits that when a job is replicable, like an “assembly line worker or fast-food server,” it is relatively easy to measure the value contributed by each worker. These workers are therefore entitled to what they earn. He finds the productivity of high-income earners harder to measure and believes their wages are in the end “largely arbitrary.” They reflect an “ideological construct” more than merit.

Soaring pay for corporate “supermanagers” has been the largest source of increased inequality, according to Mr. Piketty, and these executives can only have attained their rewards through luck or flaws in corporate governance. It requires only an occasional glance at this newspaper to confirm that this can be the case. But the author believes that no CEO could ever justify his or her pay based on performance. He doesn’t say whether any occupation—athletes? physicians? economics professors who sell zero-marginal-cost e-books for $21.99 a copy?—is entitled to higher earnings because he does not wish to “indulge in constructing a moral hierarchy of wealth.”

He does admit that entrepreneurs are “absolutely indispensable” for economic development, but their success, too, is usually tainted. While some succeed thanks to “true entrepreneurial labor,” some are simply lucky or succeed through “outright theft.” Even the fortunes made from entrepreneurial labor, moreover, quickly evolve into an “excessive and lasting concentration of capital.” This is a self-reinforcing injustice because “property sometimes begins with theft, and the arbitrary return on capital can easily perpetuate the initial crime.” Indeed laced throughout the book is an almost medieval hostility to the notion that financial capital earns a return.
