Economic theories

Here are a couple of theories about what brought on this financial crises. They are really the same theory, but one is in written form, and one is in video form. I forget how to put in the link, so i'll just paste it. This first one is the written form, and is courtesy of mrdarius' comment on aras' blog. http://ibdeditorial.com/series11.aspx

This second version is the visual form http://www.youtube.com/watch?v=H5tZc8oH--o
I'm not going to claim this is the correct theory, or even the theory that i believe. I haven't really made up my mind yet, but it makes at least as much sense as any other theory i've heard. Both are clearly biased for McCain, but that doesn't contradict their arguments, just that they have chosen to highlight good things done by McCain and bad things done by Obama. But blame is irrelevant, more important is whether the arguments are accurate, and if so, what can be done to fix the problem.
