Too Fast, Too Little?

Yglesias fears that financial reform, unlike HCR, won't get the due diligence it needs:

[T]here’s no real consensus among reputable analysts about what should be done. Is the existence of big banks a problem, or does Canada’s stable and highly concentrated banking system prove that it’s a red herring? Should we fix the ratings agencies by regulating them more stringently, or do we need to deregulate and increase competition? What should happen to Fannie Mae and Freddie Mac? Given that we need to limit leverage, how much should we limit it before we start adversely impacting growth? The bill substantially punts on these questions, either not addressing them at all or else merely instructing regulators to come up with an answer.
