I've heard several ways proposed to claw back the AIG bonuses. One way I've heard is that Congress wants to make a tax targeting AIG to get the bonuses back that way. But would that be a bill of attainder? How an you have a tax that targets one corporation? And then I heard the stimulus bill at one point had language that retroactively would have blocked "excessive" compensation, but it was eventually removed. In any event, how can the government retroactively take away people's earnings? Isn't that some kind of ex post facto law?
