It’s Krugman’s lastest manifesto in the NYTMag. It’s all here: how economists were in love with capitalism before the Great Depression (?), how Keynes was the only one who saw the failures of laissez-faire (!), how economists fell in love again with markets in recent years (!!), and how the popping bubble has startled them whereas the great Keynesian Krugman knew it all along (??). Oh, and by the way, there is no one who ever existed named Hayek or Mises or Haberler or their students.
The whole thing reads like a big fairytale, and the author is the hero in the end.
