If you get a chance, take a look at the film "Maxed Out." It is an eye opening view into the world of the Credit Industry in America and the potential decline into a two class system (debt and debtors).
The movie has an obvious political slant, but (for once) I was agreeing with him. Also, had my man Dave Ramsey, but I could not be sure if the film maker was painting him correctly. If you did not know him, and his stance on personal responsibility, you might think that he's a little stuck on himself, especially the story of getting his jaguar repo'd. He often uses sarcasm and is sometimes self effacing.
Anyways, right up there with "Super Size Me" and "Kilowatt Hours" as another favorite documentary.
