Ok. Youse gotta watch this video, referred to me by my friend Mike Waltz. It's at www.charlierose.com, and right now it's on the front page of the website. Otherwise, search for "Authors Joe Nocera and Bethany McLean". Warning: This will take about an hour. OTOH, it will take you longer to read their book.
Best exposition yet on the causes of the crisis. Maybe best forever.
