It is RIDICULOUS how hard it is to kill a company.
Absolutely, fundamentally ridiculously near-impossible.
If a large company comes close to actual death, 'too big to fail' kicks in and someone buys them up (and they keep going in roughly the same fashion), or a government hands them a wad of cash with zero alterations to their methodology.
Don't worry, though, their fuckups will kill people. It's just that they won't be held accountable.
