Oh, it's no surprise to me that the Democrats as a whole didn't do much. While there are some more progressive Democrats who wanted tighter regulation, there are still plenty of Democrats in Congress who are beholden to Wall Street. Especially to one of the worst offenders of this financial crisis, Goldman Sachs.
As George Carlin said, the politicians are really irrelevant. Both parties have long been bought and paid for by the corporations.
Here's a good example of one of the best things proposed that should have become a law out of this crisis but didn't:
Al Franken - Wikipedia, the free encyclopedia
In May 2010 Franken proposed a financial reform legislation amendment which would create a board to select which credit rating agency would evaluate a given security; currently any companies issuing a security may select which company evaluates the security.[74] The amendment was passed; however, the financial industry lobbied to have Franken's amendment removed from the final bill.[75] Negotiations between the Senate and House of Representatives, whose version of financial reform did not include such a provision,[76] resulted in the amendment's being watered down to require only a series of studies being done upon the issue for two years.[77] After the studies, if the SEC has not implemented another solution to the conflict of interest problem, Franken's solution will go into effect.[78][79]
And you can bet that some useless solution will be put in place instead.
Essentially, the rating agencies had a conflict of interest to give a security the best rating they could. Why? Because the companies could shop around and get the best offer for their security. And the rating agencies only got paid when the companies took their rating.
It's such a blatant conflict of interest and shows why junk 'subprime' mortgages were given AAA ratings by Moody's, etc. AAA ratings are reserved for the best of the best.
