The Coming Collapse of the Middle Class
Here is a great talk by Harvard Professor Elizabeth Warren on the upcoming collapse of the middle class. The first 5 minutes are spent on introducing Professor Warren, so I recommend skipping to roughly 5-6 minutes into the video. She gives a very, very interesting comparison of the changing socio-economic factors between 1970-2007. The talk was given on the 8th March, 2007 at Berkeley.
