Plus the difference ordinary marksmen and superheroes have are the fact that they're walking armies with everything to gain if they simply exploit society as-is, with all the leverage being a one-person-army, connections to both the state and other superheroes, and a stable life when you uphold the status quo gives you

Superpowers simply change material conditions massively, and the more widespread they are and the more general their use case they become incentivised to, instead, guarantee their own rights as a class of heroes rather than the class of people (and I argue this limits the likelihood of communism as an end-result) and might descend into near feudal conflict, with the ruling class constantly at their throats due to the natural antagonism between them (though this depends on how you define superheroes, where they could even count as producers if you include korean genres)
