I don't understand her thesis. She seems pre-occupied with a lack of regulation in the financial system but doesn't provide detail.
I think its pretty obvious that the financial meltdown and subsequent credit crunch was due to the sub prime mortgage problem. Government pushed banks and other financial insitutions to reduce mortgage lending standards in order to meet government set goals for more home ownership. Wall securities collapsed because of those bad mortgages not because of a lack of regulation. The government was fueling the problem from the outset.
She's right about greed though but government is supposed to look out for us, not create a climate for potential disaster. Wall street overlords will happily pocket fat commissions and bonuses but they will be even more eager to do so when government browbeats them into ignoring decades of experience with mortgage defaults.
The financial meltdown is a failure of US government housing policy more so than a lack of regulation of the financial system.
