Understanding the Financial Crisis - X

Here's a nice description of the economic crisis. Its seems fairly straight-forward, but a little simplistic. Maybe the truth is that it really is that simple and all the rest of the stuff I'm trying to figure out is just distracting me from the real answer. I don't know. But, this was an interesting piece and, at the least, sheds light on one of the facets of the crisis.
