I'm all for any stalling technique, because you never know what can happen when you buy time. While I agree that no serious effort has been made to address "too big to fail," that doesn't mean that smaller fixes aren't being addressed, and I think there are those committed to doing something about "too big to fail," who might win out before it's too late.
Beyond that, I don't think "too big to fail" was ultimately the root cause. Bad loans were. You can argue that bad loans came out of "too big to fail," but if they can address the bad loans, that is half the battle.
I will readily admit that I am not an economist, and it was never a field of study of mine. However, I know enough to know what the bigs failing last fall or earlier this year could have meant, and found it terrifying. The so-called "creative destruction" of it would have been too much for the country to absorb, imo.
I think a reading of TARP & its success depends largely on what impact people not only would anticipate without it, but what they would be willing to absorb if they agreed on how bad it could have been....
