How else would they pay their rent?
It's... really not clear how superheroes pay their bills. Granted, we know Peter Parker works for the Daily Bugle and fights crime at night. But what about Captain America? Does S.H.I.E.L.D. pay really well? How would they even get a guy who's technically been dead for 70 years onto direct deposit?
Imagine for a moment:
Clint Barton: the hard-of-hearing Starbucks barista.
Natasha Romanoff: the night club bouncer.
Steve Rogers: paying his bills after monetizing his YouTube account.
How else is he going to pay for his ridiculously expensive apartment in DC?
