Everyone agrees that excessive pumping of money into the system will cause inflation. The problem is figuring how how much is, in fact, excessive. And in a recession, you can't just say "let's err on the side of conservatism and not pump anything in" because there's the risk of deflation on the other side.

"We stand today at a crossroads: One path leads to despair and utter hopelessness. The other leads to total extinction. Let us hope we have the wisdom to make the right choice." —Woody Allen
