A look back in time; Ben Stein was also an idiot back then

PZ Myers links to a description of the newest stupidity of Ben Stein's economical advice. It's rather painful. However, even more interestingly, commenter JP points us to an old piece by Ben Stein where he accuses Paul Krugman of having a "limited background in economics".

Wow.

Paul Krugman is not one to mince words, so his response is quite entertaining.
