Worried about the national debt? Donate money to pay it down!

With the national debt growing at a frantic pace, a lot of Americans are terrified about what it will mean for our economic futures.

On average, about five donations are made per week and so in 2009, there have been just over $3 million in donations -- whose impact was quickly reversed by government spending on just 666 clunkers under the Cash For Clunkers program (funny how that math works out, just sayin').
