The crash was caused by the collapse of the housing bubble. The housing bubble was caused by the government (yes, including some liberal Republicans like Bush) forcing lenders to make politically-correct loans to "eliminate the racial gap in housing".
I know you don't actually believe what you just typed, so I won't dignify it with much of a response.
Suffice to say that the "Community Reinvestment Act caused the GFC!!!!!1111" 'theory' has been thoroughly debunked, to the extent it was taken seriously at all - not least because, as Ernest points out, the vast, vast majority of subprime lending was by banks that weren't even subject to the Act in the first place.
Here's the remarks of Randall Kroszner, who was one of the Governors on the Federal Reserve board. And, since you'll undoubtedly dismiss this, a member of the Bush administration and notable Chicago school economist - not exactly a bleeding-heart socialist. 
But by all means continue peddling the kind of bulls--t that only persists in the racial fantasies of Free Republic posters. It's not like you're going to listen to me, or do any research at all.
I'm not saying Krozner isn't right (he might well be) but him being from the Bush administration doesn't lend him credibility in the direction you are suggesting. W. Bush agreed with CRA-type policies - it was part of his vision of the "ownership society."
