When corporations start buckling during sharp economic downturns, everyone's first instinct is always "let them burn."
But it's often not a choice between letting entire swaths of our economy collapse, and dumping absurd amounts of our tax dollars to prop up these poorly-run companies. We can give them loans with strings attached, force them to go through bankruptcy, wipe out the shareholders but preserve the structure of the company, bail them out but subject the industry to much greater regulatory scrutiny, etc.
Personally, I wish we had a straightforward way to bail out a company and have the U.S. government take ownership in the company until the stake can be safely unwound, or the too-big-to-fail company can be broken up. Theoretically, with a controlling stake and the corresponding board seats, you could force out the lousy management that didn't take adequate precautions as well.
It'd kind of be socialism-esque nationalization of industries with extra steps, but Japan has been doing a similar-style thing since the 90s, and I can't imagine it would be any worse than the relatively strings-free bailouts we've seen, or the collateral damage and runaway collapse that would occur from letting a monstrous chunk of the economy fail all at once.
