I mean Batman's whole shtick is that he's a rich guy who goes out at night and beats up poor people.
Mr. Fantastic's shtick is that he's a middle-class academic living the American Dream (The first verse of David Byrne's "once in a lifetime" essentially). And sure there's class issues and mandarin issues to consider there, but it's so fundamentally harmless as to be irrelevant.
The problem with superheroes is similar to the issues we have with police irl, we are asking too much of them, we are asking them to handle issues far beyond what they were meant for.
It's never good when one genre sucks up the oxygen. It used to be action movies, then fantasy movies, musicals in the '60s, Westerns for a big while. Now it's the superhero genre.
If the superhero genre stuck to its lane, it wouldn't be an issue but since it has so much scrutiny and free real estate in people's imagination, it kind of has become this immovable thing.
