A series of videos this morning to explain how banks warped the normal rules of supply and demand to create the bubble that became the U.S. (and UK!) sub-prime mortgage crisis.
I like these videos because the guy lands with me as having no particular axe to grind - other than what works sensibly and what doesn't.
I also think his style is attempting to explain this stuff - while most financial people have a vested interest in obscuring the simple truths involved.
