Elizabeth Warren is a law professor at Harvard and has become a public figure recently due to her leadership role on the TARP Congressional Oversight Panel. She's also an expert on trends concerning the middle class. In this lecture at U.C. Berkeley in 2007, Ms. Warren discussed why the quality of life and financial security of the middle class has diminished year after year for the past 30 years. Not a pleasant subject, but it's an important topic. I hope you find it informative.
