Sections on Banking, Credit Crisis, Current Economics, Finance, Paulson Bailout, and some smaller sections.
http://www.khanacademy.org/As for my OP, the book "The Big Short" is eminently readable for anyone who can read at the Harry Potter level. It covers the market players at a personal level similar to a thriller during and up to the failure of Lehman and has a postcript. It also covers some of the technical features of loan packaging and the organization of the market for financial products.
