Is The Piketty Bubble Subsiding?

 Is the Piketty bubble subsiding? "The Piketty bubble may be coming to an end. Economists are starting to criticize the heart of his argument. That is not to diminish important aspects of his book. But the most profound of his claims simply may not hold....In the long run, I think Piketty's work will indeed prove seminal. It will force economists to deal with the remarkably wide range of issues he raises. But he hasn't replaced Marx with a more well-founded model of capitalism's unfairness." Jeff Madrick in Naked Capitalism.
