The only major piece of regulatory legislation enacted during the Bush years was the Sarbanes-Oxley Act, which dramatically increased regulation of corporate financial disclosures. The really big regulatory changes being pointed to now as possible culprits for the crisis date back to Bush's predecessors: Bill Clinton, Ronald Reagan, even Jimmy Carter and Gerald Ford. So the popular Democratic refrain that "Bush-era deregulation" is to blame for our troubles is a little hard to square with the evidence. What is true is that most Bush-era financial regulators were less than enthusiastic about the very act of regulating, and that Bush's "ownership society" push glossed over a lot of potential dangers. Bush didn't cause the financial regulatory breakdown, but he didn't jump in to fix it either.
