Nah really this last crisis was more a issue with a rise in a new financial sector (Shadow markets) that had almost no regulation. The banks did get sucked into it, but it was more due to the massive profit that they were able to make.

The financial crisis was created by Democratic feel good policies designed to put people in homes who had absolutely no business owning them.
The regulatory process that failed was roundly dismissed by Democrats when it was becoming clear that Fannie Mae, and eventually Freddie Mac, were unsustainable.
mindset fails to figure in that the 'mac banks were making home loans from the 30's and never had anything near the issues that came about in this crisis.
These problems formed when the shadow financial systems found they could package these and sell them to wallstreet for an insane profit. So they (see quick loans) came up with all these new packages to sell and hit everyone and anyone with them, later dumping it on the Mac banks that were not prepared for it.
If you look at the mindset of the last few Fed chairmen you can see a shift in the mindset.
In the 50-70's they tried to curb the behavior, they said something along the lines in the 50's that the fed was there to over see the party and to pull away the punch bowl when the party started to get ramped up.
Where Greenspan in the 87-06 took the stance of over seeing the party and allowing it to get out of hand but to be there to be the designated driver so everyone gets home safe.
