You don't address the fact that they paid out bonuses for doing a horrible job just prior to the seizure, nor the very real danger of further concentration of the banking sector (We are down to the big 3 now?).
The issue isn't that too big to fail happened, because its immaterial after the fact. Its that little punishment was actually done for bad management, and not only that, the situation is left worse because we have a banking concentration problem.
If you look at the number of banks chartered after 2008, its dropped to negligible amounts going into the business, and regulation has only been increasing. You have to lie to get a charter because no reasonable person would accept the personal liability without something in it for them. The requirements are that onerous.
Everything is now so big it will certainly fail, and that's what people are angry about. There is plenty of evidence over the past 100 years (and longer if you go further), that as sector concentration goes up, so does corruption, frauds, and other crimes that are largely based around deception at our loss. It becomes easier to increase the scope, and get away with it when setting up dominoes to fall (so you can profit on event's you manufacturered).
The fed aren't doing there jobs, and worse, it looks like they could never meet their original charter to begin with. They aren't government, they are private bankers.
So they try to justify bailouts as a way of saving the system, and really its just acting as a wealth transfer to the elite rich whose pockets they are lining via a money printer at the expense of the public taxed by inflation.
