George Will is a standard-issue right-wing blowhard, notable mainly for his outfit (tweedy in a 1950s academic way) and prissy demeanor. Paul Krugman is a Nobel prize-winning economist. So when the two men spar it’s hardly a fair fight, much closer to Bambi v. Godzilla than Ali/Frazier.
In this clip, Will offers the standard conservative view that FDR prolonged the depression. It takes Krugman about 45 seconds to show why that’s all wrong.
