financial crisis. There are many well documented and studied reports.

I like the following by William Barrett, which sums up in lay men's terms, what happened:

"Andrew Cuomo took actions that—in combination with many other factors—helped plunge Fannie and Freddie into the subprime markets without putting in place the means to monitor their increasingly risky investments. He turned the Federal Housing Administration mortgage program into a sweetheart lender with sky-high loan ceilings and no money down, and he legalized what a federal judge has branded "kickbacks" to brokers that have fueled the sale of overpriced and unsupportable loans."
