Sounds like Uber provides valuable service to the poor who are more likely to work night shift and also less likely to be able to afford the premium for the nicer black cab service during the day.
> Sounds like Uber provides valuable service to the poor who are more likely to work night shift On what planet are "the poor" commuting back and forth to work via Uber?
Most public transit services have reduced service on nights and weekends; so, in a world where you don't have a car; you can take the train/bus to get to a shift in the day, but must take a cab or uber home.
It seems obvious that Ubers or Taxis would serve this purpose wherever vehicle ownership is cost prohibitive and public transit is at all available.
Likely, this isn't "the poor" but inclusive of much of the working class in modern cities.
