For Fuck sake, President Obama better get his act together on this issue. To make banks smaller or to separate functions of the bank is a half-ass response to public anger.
To break down the Credit Crisis is not that difficult.
There were a tun of fuck ups at the ground level, including the 'main-street' part, all the way to the top of the large institutions.
But a few simple enforcement of established regulatory rules (at the ground level), and some new margin requirements for the investors, will force continued responsible lending and a prevention of 30:1 leverage scenario that crushed Wall Street.
There is no need to separate bank institutions, the solution is just a function of putting common sense rules in the works and enforcing the already established rules!
Establishing new margin requirements and enforcing good regulation is not difficult to do. Theatrics on declaring war on the responsible banks that survived are not necessary.
