I don't want this to come off as harsh but it's a huge city with lots of money that has a pretty large disabled community. They've been really slow upgrading their train stations but their lack of action doesn't make it OK to never fix the problem.
Keeping people from riding the subway because they're disabled is a form of discrimination under ADA. IANAL but I think cities like NYC need to have a plan for upgrading accessibility features and show progress month over month. Failure to make any progress would probably leave them liable for violations of the ADA + Rehabilitation Act (that's what happened to Boston's MBTA). With the threat of a lawsuit, it's probably cheaper to just get a plan and start upgrading stations. Plus, it helps people.
physical disability affecting ability to walk upstairs and downstairs? i doubt that
according such statistics it's also half of the women experiencing domestic violence, when you tell your wife you wanna watch different TV show than her, it's some verbal abuse or violence and similar crap with rape statistics in Sweden
