Ben Bernanke, current chairman of the Federal Reserve, testified before Congress this week, and during that testimony, several congressmen made reference to the idea that, if we have truly left "too big to fail" behind us, why are several of the nation's largest banks still being priced on the market as if they are indeed too big to fail? In this video, Motley Fool financial analysts David Hanson and Matt Koppenheffer discuss just how big some of these banks like Bank of America (BAC -0.13%) or JPMorgan Chase (JPM 0.05%) really are, and why it is very unlikely the U.S. government will allow them to truly collapse.
