Bubbles Krugman pulls the rug out from under his diehard defenders:
The hangover theory, then, turns out to be intellectually incoherent; nobody has managed to explain why bad investments in the past require the unemployment of good workers in the present. Yet the theory has powerful emotional appeal. Usually that appeal is strongest for conservatives, who can't stand the thought that positive action by governments (let alone—horrors!—printing money) can ever be a good idea. .... And some people probably are attracted to Austrianism because they imagine that it devalues the intellectual pretensions of economics professors. But moderates and liberals are not immune to the theory's seductive charms—especially when it gives them a chance to lecture others on their failings.
