Why has there been no investigation as to why Moody’s and Standard & Poor’s gave these CDO’s such high ratings? Was it their stupidity or was there some type of collusion or kickbacks involved. Could there have been ‘pressure’ from the government to get more people to buy homes? Some people understood the risk and bought the Credit Default Swaps. And, can we trust Moody’s and Standard & Poor’s to do a good job in the future?
Robert Cringely says that Wall Street has been able to put Collateralized Mortgage Obligations back together since they were first developed in 1973 (http://www.cringely.com/2009/03/the-not-so-bad-bank/).
Sounds sensible. But if he's right, why would I have first heard it from a technology writer?
I think one important thing not covered in the video is that the CDO are used to enhance the credit of the assets in the tranche.

The regulators fail to properly asses the credit risk because they treat the assets in the CDO to have independent risk of failure when in fact they don't as the above video demonstrates.
The causality is also wrong. The top tranche doesn't get filled up first because it is the least risky. It is the least risky because it gets filled up first. Good video though.
