Maybe not rich but a lot of the lower income people in my neighborhood in Brooklyn aren't using Uber or Lyft regardless of how cheap because they don't have much money period. You have to have a phone and internet access for these services so it's definitely not hitting the lowest brackets.
Brooklyn is a big place, and the person you're replying to did just say his neighborhood… probably little data available on any scale let alone the scale of one's neighborhood, aside from anecdotal.
