Actually a really good video. Certainly not complete but addresses the top down demand and does it in a way that is very easy to understand.
The only part I can see that is missing is how we got to point that home values had been rising so fast and for so long. This is where the story starts in the video but it is really the middle of the boom.
To understand how we got to the point investers were even interested in CDOs, you have to look when and why home prices started accerating much faster than inflation. Couple this with the telecom crash and low return on T-bills, and you have a gov't created bubble. There are whole threads dedicated to this, so we probably don't need to get into it unless some one is curious and hasn't read the other threads.
The part it leaves out is very important, but the rest seemed pretty accurate to me. Bookmarked.
Oh yeah...almost forgot.
You are a republican partisan hack. You know it was all Bush's fault but you're too busy sucking his dick. ...and something about Iraq.
There, I got it out of way for you.
