I hate to break it to you, skippy, but the housing bubble was caused more from private lenders than public ones.Petition the government? Dude, Clinton went around talking about housing being the American Dream, then his administration threatened the CEOs of all the major financial institution to lower credit standards or he'd have their asses hauled into endless Congressional investigations. The Fed followed it up by flooding the market with endless ultra low interest loans and underwriting. This is on top of how the mortgage deduction skews prices and doesn't actually make housing more affordable. To say that was driven by the market is just a flagrant rewriting of history.
The default rate for private lenders was 6 times that of public lenders.
The loans to borrowers with lower credit scores which the GSEs bought up fared much better than did similar privately-securitized loans. (Six times better, according to the Center for American Progress). A Federal Reserve report using different methodology "found no evidence" that government policies designed to encourage lending to lower-income borrowers had contributed to the subprime bubble.
MediaNatters? That's lame even for you.
Of course many private lenders worked in subprime, which naturally has a much higher default rate. SO it's an unfair comparison. Looking at the plain vanilla market the private lenders will have exactly the same default rate because they underwrote the loans to FAn/Fred standards.
