Remember the collapse from the housing bubble burst? Who predicted that? Precious few men and women knew it was coming, and damned near none had any idea how bad it could be.
Jesus H Christ! How about everybody aside from lefty morons? It was inevitable as soon as Fannie Mae and Freddie Mac were more-or-less required to lower their lending standards by legislative fiat.
Go back into the record and note the conservative opposition to these bills, based on exact the perfectly predictable end results you are whining about.
We had something like 2000 years to develop standards for loaning money, guess what, when you piss that away for social engineering, this is exactly what it going to happen. The current "fixes" actually make it worse, so you also have to have a spate of new regulation to prevent the banks from kicking people out of their house for the insignificant problem that *they can't afford to pay for it*. Then you bail out the banks with taxpayer money. It's a death spiral.
