In his New York Times column of April 25 of this year, Paul Krugman wrote, “The really striking thing about the debate so far is that the right seems unable to mount any kind of substantive counterattack to Mr. Piketty’s thesis.”Here is that substantive counterattack, in the form of my essay “Piketty’s Capital: Wrong Theory/Destructive Program.” In it, I show that Piketty's destructive program of confiscatory taxation of income and capital derives from his lack of essential knowledge in the areas of the theory of capital, profit, and saving.My essay is not only a critique of Piketty but also an introduction to sound ideas in these and related areas.
