Cash for anything?

First cars, now guns... Maybe this guy is onto something in suggesting that the housing market needs a "Cash for Clunkers" program to help it get moving again.

Better yet, how about a "Cash for Cash" program where you bring in old, worn out bills and the government gives you a slightly higher dollar amount of brand new bills. That would be a much more direct way of stimulating the economy - bring in an old $100 bill and, in return, get a newly printed C-note plus a crisp new $20 bill.
