It almost did once but Superman saved the day. Then he turned time back and saved Lois Lane too. Superman is awesome. Way better than Batman, who has no super powers, just a bunch of widgets.
I've said this before, and I'll say it again, if you really think about, superman is not only a commie (I'll get into that later) but really, an a$$hole. Let's examine:
We have superman, endowed by his Kryptonian biology and earth's "yellow" (actually white, but that's beside the point) sun with superpowers including: immortality, bulletproof, super speed, super strength, heat vision, cold breath, x-ray vision, and he can fly....basically the ultimate jock.
And his arch nemesis, lux luthor who is...wait for it....smart. That's it, no superpowers, just smart. So lex, in true capitalist fashion, decides to make a buck, of course, he's got a weird streak and flexible morals, so his ideas could best be categorized as schemes, at the beginning, but rather than simply instructing lex that it's far easier to make vast piles of money legally if you are beyond genius smart, superman basically foils his plans with ever increasing levels of jock-titude, teaching lex, instead, that super genetic freak jocks will always win (and get the girl) over lowly super smart nerds. Needless to say, this causes some angst, and he strikes out at his tormentor, superjock, with increasingly outlandish plans, putting the rest of the world into a position as bystanders to "revenge of the nerds 16: nerd strikes back with doomsday weapons".
So it seems the moral of the story is "smart capitalists who thrive on personal responsibility and try to make things happen for themselves will always lose to genetically superior superjocks who want to save everybody, protect the world".
Needless to say, thinking about that, one can't help but pity lex for not having a good Econ 101 teacher, and look at superman less like "hero of humanity" (odd, given that he is an alien) and more like the big angry guy in revenge of the nerds pummeling the smart kids because they convinced the other retarded jock worshipers to give him their lunch money.
