Krugmanese

Harvard economist Greg Mankiw:

Of course, if one defines "grownup" as a person who agrees with Paul Krugman, and "hack" as a person who does not, then one might come to a different conclusion.

The important thing is not Krugman or his opinion, but the fact that nothing proposed by Team Obama will fix the economy. It's all warmed-over Keynesianism, and it won't work. But when it comes to simple arithmetic, Mankiw smokes Krugman.
