Honestly a big issue seems to be in other countries, especially ones like Japan people frequently site as the model for public transit, transit is privately run and developed more pragmatically/more profitably. There wouldn't be sense in adding useless screens with useless information, but there sure would be a lot of consideration on how we can make our station more attractive than a competing line's station, paring down overhead to its most base items to further that goal.
Whereas here in the US, its like transit departments are handed budgets generated by tax dollars but no clear direction or plan for how to maximize those dollars. So they have to turn to subcontractors who eat through the pile of money like a vulture eats carrion. This is a system that over time lobbies to further entrench and sustain itself and becomes impossible to rip out and restart. If you go advocating for privatizing the transit system you'd be likened to Judge Doom before people stop and think for a second of what that would actually look like: the shinkansen for example.
