Where are these talented people going to go? If there are still banks around that are able to pay them what they want (without taking bailout money), why is there a need for the bailouts at all?
This is a crappy analogy to what we're looking at. It's not just the bankers at the top getting the bonuses, it's the traders, the front and back office, legal, every bit of the business that brings in money (or not as the case may be). It's a systemic problem requiring a systemic solution.
