At lunch yesterday someone told us about this radio program on This American Life.  Its called the Giant Pool of Money and is by far one of the best explanations for the housing crisis we had ever heard.

Its is an hour in length, but trust me you will be so hooked on the story telling it will just pass by.  Its explained in the most everyday terms, and involves sound bites from real people through out the chain.

Anyway, go have a listen yourself.  I really do recommend it.
