Let it hurt. Unless investors feel it (and they only feel via the value of their investment), nothing will change, ever. Of course, you'll get plenty of people saying that it's unfair that this time they really have to live with the consequences of their risk management and that we should totally do that, starting tomorrow. But then you'll get the next cries next week when they've done it again.
Mind you, I'm not talking about some restaurant that's more or less getting by without generating large profits, but every company that spent their money on stock buybacks will now have to do the reverse: issue more shares to recapitalize.
