Mankiw vs. Greenspan? Mankiw is saying that growth, spurred by the administration's tax policy, will increase the government's top line and reduce the deficit.  Greenspan is saying that deficit's are bad when the economy is at full employment.  It's not clear that these two men would disagree with each other.  What counterposes their opinions?

The only difference seems to be the writers' editorial bent.  ¶ 4:01 PM
