I'm not sure what all the noise is about. Sure, $2 billion is a lot of money, but it was shareholder cash. So far as I can tell, no depositors or other 3rd parties lost a dime. Certainly the taxpayer was not on the line in the same way as Solyndra.
Deregulation of the banks and investment houses has resulted in a stronger financial community. It's not clear what would have happened if we had the same banking system that existed before deregulation.
