This week, Krugman makes one decent point: successful businessmen aren't necessarily any good on economics. No argument there. Krugman doesn't quite get why his insight is true, but at least it's something. Bob and Tom discuss (1) why government can't be run like a business, (2) why falling wages need not be a catastrophe for "aggregate demand," (3) whether it makes sense to speak of a "manager" of the economy, and more.
