Superheroes, are presented as by their nature disruptions to the "natural order" of the world. That is to say many are presented in worlds more or less analogous to that of the reader, either in the urban setting or something that perceivably realistic. But, this presents a disruption to the world they exist within.
Many heroes are, in some interpretations, read as virtual gods amongst men, invulnerable, nigh unstoppable, with only "benevolence" as the check against them dominating the world. How does a world function similarly to our own while also inhabited by a living god or gods?
Many exist only in reactive states, that is to say, many heroes and their stories are written to respond to "crime" or "disasters" but rarely are we presented with them proactively pushing for some sort of shift. How does this materially affect their world? How does a world of heroes and supervillains, one of constant impending doom have any sense of normality? How can that world even function?
Part of this can be blamed on the medium, crime being punished is an easier comic to sell than crime never happens, but that reinforces the idea of crime without interrogating the why of crime. The material conditions, not to mention the motivations of criminals within worlds of sentient nuclear weapons is rarely examined.
Returning to the core question, superheroes exist in worlds similar to our own, but how in fact is that possible? How is it that a world where Superman and Batman exist is virtually the same as a world where they don’t. How is the world of Marvel, with aliens and spirits, and devils, and sentient robots not dissimilar entirely to the world that exists today?
How do writers square the circle that is the "status quo" ? Status quo being read as a world that has enough parallels to the real world to be read as similar to our own. A sense of normalcy that can allow for the reader to feel connection with the world of the heroes. How can you reckon with the fact that the existence of these walking myths has little impact on their worlds?
The writer could interrogate the idea of the superhero as it compares to the prior age of myth, but the more challenging question would require some understanding of the main universes of some of the major comic book publishes and their distinctions and similarities from the real world along with speculation/analysis of why or even how those similarities exist.
One idea from the pilot episode of Agents of SHIELD: organizations like SHIELD exist to keep the majority of the weird stuff away from the public, so the world will not change dramatically.
Another idea: if the existence of super-people did change the world, the most likely result would be something like Injustice: Gods Among Us - the super-people ruling the world, whether the regular people wanted that or not. Many of the superheroes know this and willingly avoid impacting the world in such a way because free will matters to them.
Also consider Watchmen, a fairly popular story about super-people very much changing the world. – noahspud4 weeks ago
