The good people at Brave New Films have put together a video that might give you an inkling of how much $3 Trillion dollars is. If it doesn't accomplish that, it certainly illustrates how difficult it is for an individual to fill up their own $3 trillion shopping cart. Think you can do a better job than George Bush? Go for it and then pass on a gift certificate to one of your friends so they can take a turn.
(Full disclosure- okay, I'll admit it, I threw a Wii and a tropical island in my shopping cart, but the rest of my $3 trillion went to noble and peaceful causes, really!)
psssst, Do something!
