This is the only change I don't like. She's from the hood, poor, but she's resourceful. In the comics, she made money by selling her patents...similar to how Reed ended up getting the F4 out of poverty. But she was still poor, because she used it for supplies. She really has no interest in money.
Nah. Spider-Man is the poorest of them all. Daredevil is poor. Jessica Jones. Matter of fact, outside of Rand, all of the street level heroes are poor, or paycheck to paycheck at best. Punisher is the other exception, because he robs stash houses. Most of the X-Men are poor. There are far more poor than wealthy.
Even in this show, it doesn't show her being Spidey levels of broke, she just can't afford to maintain her tinkering. Like
@Rhapscallion Démone pointed out, "genius without funding" is a common trope for the genre. Hell, Flynn was broke in Tron. The plot was his breaking into ENCOM to steal evidence that they stole all of the games from him.
