"Remember what happened. Through a series of events in the mid-1990s, Congress increased the supply of credit for home mortgages, through the institutions Fannie Mae and Freddie Mac. They were essentially given too much money for political reasons.
"And then that was followed in New York by the repeal of Glass-Steagall which then allowed banks to use investment equity vehicles to create liquidity which creates very large amounts of money. So the banks are busy creating money and making a lot of money on that creation of money and the regulators were either, depending on your point of view, asleep at the wheel or did not have the tools to understand what was going on."
