With all due respect, Quixote, he had a GREAT deal to do with it, as did the democratic party even during Bush's years (and preceding them truth be known).
Those "high risk" loans weren't that risky when times were good, now were they? And who was pushing them / actively encouraging them? The bleeding heart, illegal alien loving libs (and I have TONS of respect for LEGAL immigrants, but believe the word ILLEGAL should still mean something). The reason the failures are occurring now that the dems encouraged/paved the path for the failed investments, and now are killing business investment and re-investment, creating record unemployment, and record mortgage failures. And they only continue to push practices that are making matters worse.
Don't make me spend valuable time laying it out in greater detail... how about I let an article from the lib hot-spot of Boston do it for me (you'll note they say the seeds for the meltdown go back to Carter).

Like I said, someone's going to have to be mighty brave to make a dent in this mess, and Obama sure is NOT that person. No he's to busy encouraging today's lib rally, to counter the patriotic one held on 8/28, with folks forced to attend from groups like:
Green for All
Rainbow PUSH Coalition
SEIU
Chicago Democratic Socialists of America
Code Pink
Communist Party USA
Democratic Socialists of America
Gay, Lesbian and Straight Education Network
Gray Panthers
International Socialist Organization
Planned Parenthood
Ya Ya Network
The libs across the nation today must be so proud...
