Anything that's too big to fail is collected into a new Bank of the United States, which is safeguarded until it is out of the danger zone.

And even once the bank is strong enough to stand on its own, things like credit futures, and control of the electronic credit system (debit cars, etc.) should  be permanent.  If the government is expected to pick up the bill when things fall down, why shouldn't it just operate all the time, and covert any profits into government revenue. Not to mention that control over electronic transfers would give tax authories a wealth of information that could be used to prosecute tax cheats.

As for the local branches, why not mutualize them, and limit their scope to a single state?

And I'll give my consent to any government that does not deny a man a living wage-Billy Bragg
