I get that a mortgage crises was a major contributor to the current state of the economy but honestly I had no idea - I really didn't understand sub prime or why banks loaned money to people who couldn't afford it. Coming back from film club and while cooking dinner earlier I listened to This American Life from May 9th titled Giant Pool of Money - and I now have a much better sense in what developed, and am infuriated that it was allowed to. It is a fascinating listen.
