Writing this now I see your point was not that they aren't extraordinary, but rather the opposite of anti-wealth. I don't disagree, but I'm not claiming that every movie covers the same ideas either. However, the villains of Spiderman 2, for instance, are a bunch of Iron Man's lower level former employees who specifically call out how they got the short end of the capitalist stick, and how unfair it is that he got the spoils of everything, and how easy it was for him to dispose of them. The villains of Spiderman 1 are just some construction guys who got shafted by the collateral damage of the heroes and are trying to make a living wage. Yes; I do recognize the irony in that both of these working class groups are villains, but they're not meant to be portrayed as "Evil" for the most part. Again, not especially deep, but not "I'M GOING TO DESTROY THE SUN BECAUSE THATS WHAT VILLAINS DO!".
The captain america movies, seem particularly keen on the idea that the american government / law does not define the american ethos.
Professor Xavier is wealthy af. And he doesn't go around helping just anyone. His altruism is hecka parochial.
About the only common element is that the government generally sucks at doing anything. The only thing the government doesn't suck at is having at least one plucky SEAL/Ranger/Marine team out there that's fighting against the odds.
