So, uhh, the ideology of the Bush Admin, exploitation of the GSE's for their own ends and non-regulation of lending/investment entities had nothing to do with it?
Yeh, sure, low interest rates played a part, which I acknowledged all along. But that's not the whole story, at all. Any sort of self-regulation, responsibility, or restraint in the whole lending-securitization chain disappeared in the runup to the peak as greed took over. They'd qualify anybody with a pulse, even routed more qualified buyers into more profitable sub-prime adjustable rate short term loans, then worked the securitization magic to render asswipe into supposedly AAA bonds.
They treated mortgages like predatory furniture loans- nothing down, no payments or interest for one year, etc. Any consumer who doesn't pay it off before the rest of the contract kicks in gets screwed, hard. And consumers can support that because most are smart enough to pay it off, and those who don't are obligated to only a small part of their income for a short time. That's not true wrt mortgages, where consumers commit large portions of their income and simply can't pay the balance w/o refinancing.
The FRB didn't have anything to do with that.
