We replay sections from the original "Giant Pool of Money," in which This American Life producer Alex Blumberg teams up with NPR's Adam Davidson to tell the story of how the U.S. got itself into a housing crisis. They talk to people who were actually working in the housing, banking, finance and mortgage industries, about what they thought during the boom times, and why the bust happened. We hear from a mortgage company sales manager who was making over a million dollars a year and spending his time clubbing with celebrities. We meet a man who got into the mortgage industry after getting hired away from his previous job as a bartender. And we follow a Marine who was tricked into an unaffordable mortgage as he tries to save his house from foreclosure. (30 minutes)
