Cash for Clunkers

What is all this about Cash for Clunkers all over the net?It is all the rage. It sounds like a good program, but i don't have a vehicle that gets 18 mpg. The only thing I see wrong is they are destroying all these cars when there are people who cant afford any car who would be happy to have one of those instead of destroying the motors. I do applaud getting rid of all those gas guzzlers, but like I said, maybe some of them could be put to better use.
