Obama has said repeatedly that his administration will make mistakes and try to correct them. He has already decided to continue Bush policies on rendition and FISA, albeit with sensible restrictions. These are unlikely to cause political problems in the near future unless abused by Bush-era holdovers and recalcitrants in the intelligence services.
But the financial fixes recently announced are getting deserved criticism from progressive sources.
If one used the analogy of cops and robbers, this current plan could be considered placing poorly armed cops who do not know whether they can arrest crooks, or even who the crooks are, in front of banks that the crooks have already broken into, and where they are now posing as tellers and bank managers.
Into this situation he and Secretary of the Treasury Timothy Geithner have proposed poring more money and opening up the doors and waiting to see what happens to it.
The only change is that we now get to watch the robbery like some lurid reality show. Until they get the balls to tell these folks that you either use it (lend, invest) or lose it (taxes, government control) I doubt that they (the financial system) will take us (represented by government) seriously. They need decisiveness.
