That is the main issue. Nothing you can do against individuals that acted legally.

However hindsight happened very quickly, almost from day 1. There is no excuse that the bailouts didn't come with extremely punitive string attached only loosened after the law had been updated.

That did not happen. There is no moral to the story, no happy ending. Worse, hindsight works both ways. Maybe the current generation of financial company executives have learned their lesson, but the next one will have no such reserve.
