Superheroes are supposed to be epic characters in (mostly) epic stories, the modern analogues to legends like Beowulf or Gilgamesh. You can (and should) do stories that are lighter, comedic, or just "daily life" stuff because it serves to both refresh the palate (so to speak) after the previous big arc and makes the next big arc something readers care about because it disrupts the heroes' attempt at living "normally." And sure, you can incorporate real-world events into the stories too.

But at the end of the day, it has to be remembered that this is supposed to be fiction, not a newspaper presenting the headlines in drawn form. So constantly injecting reality eventually makes the material worthless because it's just as bad, depressing, and all-around toxic as the shit we're trying to get a break from by reading it in the first place.
