Picketty: All you redistributionists took away the wrong takeaway

Seems the author of last year's big hit among the pointy-heads, "Capital in the 21st Century," feels he was misunderstood:

The book’s central proposition, that inequality in capitalist societies will inevitably grow, can be summed up with a simple equation: r>g. That is, the return on capital (r) outpaces the growth rate of the economy (g) over time, leading inexorably to the dominance of inherited wealth. Progressives such as Princeton economist Paul Krugman seized on Mr. Piketty’s thesis to justify policies they have long wanted—namely, very high taxes on the wealthy.

Now in an extraordinary about-face, Mr. Piketty has backtracked, undermining the policy prescriptions many have based on his conclusions. In “About Capital in the 21st Century,” slated for May publication in the American Economic Review but already available online, Mr. Piketty writes that far too much has been read into his thesis. 

Though his formula helps explain extreme and persistent wealth inequality before World War I, Mr. Piketty maintains, it doesn’t say much about the past 100 years. “I do not view r>g as the only or even the primary tool for considering changes in income and wealth in the 20th century,” he writes, “or for forecasting the path of inequality in the 21st century.”

Instead, Mr. Piketty argues in his new paper that political shocks, institutional changes and economic development played a major role in inequality in the past and will likely do so in the future.
When he narrows his focus to what he calls “labor income inequality”—the difference in compensation between front-line workers and CEOs—Mr. Piketty consigns his famous formula to irrelevance. “In addition, I certainly do not believe that r>g is a useful tool for the discussion of rising inequality of labor income: other mechanisms and policies are much more relevant here, e.g. supply and demand of skills and education.” He correctly distinguishes between income and wealth, and he takes a long historic perspective: “Wealth inequality is currently much less extreme than a century ago.”

All of this takes the wind out of enraptured progressives’ interpretation of Mr. Piketty’s book, which embraced the r>g formulation as relevant to debates playing out in Congress.  

Actually, normal-people-type observers - as opposed to Kool-Aid-besotted types such as Paul Krugman and Robert Reich - had started pointing out the holes in Picketty's thesis some months ago:

Many mainstream economists had reservations about Mr. Piketty’s views even before he began walking them back. Consider the working paper issued by the National Bureau of Economic Research in December. Daron Acemoglu and James A. Robinson, professors at the Massachusetts Institute of Technology and Harvard, respectively, find Mr. Piketty’s theory too simplistic. “We argue that general economic laws are unhelpful as a guide to understand the past or predict the future,” the paper’s abstract reads, “because they ignore the central role of political and economic institutions, as well as the endogenous evolution of technology, in shaping the distribution of resources in society.”
The Initiative on Global Markets at the University of Chicago asked economists in October whether they agreed or disagreed with the following statement: “The most powerful force pushing towards greater wealth inequality in the U.S. since the 1970s is the gap between the after-tax return on capital and the economic growth rate.” Of 36 economists who responded, only one agreed.
Other critics have questioned the trove of statistical data Mr. Piketty assembled to chart trends in income and wealth in the U.S., U.K., France and Sweden over the past century. Are such diverse data comparable, and have the adjustments that Mr. Piketty introduced to make them comparable distorted the final picture? 

Another real-world example of Churchill's famous axiom that a lie makes its way around the world before the truth has a chance to get its pants on.
