In my previous two articles, I have shown that Paul Krugman - revered by his acolytes as the Invincible Krugtron - failed to anticipate the financial crisis and wrongly predicted that the single European currency would fall victim to it.

As I pointed out yesterday, Paul Krugman’s right to consign others to the “Always-Wrong Club” , and routinely to insult anyone who dares to disagree with him, is fatally vitiated by his own embarrassingly bad record of commentary on the European phase of the financial crisis.

It’s an ill wind that blows no one any good. The financial crisis that came to a head five years ago with the failure of Lehman Brothers has been especially beneficial to the economist Paul Krugman.
