Earlier quoted context omitted.
Replace "poor" with "black" and you have the reason public transportation has been suppressed in large parts of the US. When I lived in Atlanta a suburban city official explained that "we all know the sort of people who hang around bus stops" while killing plans to expand bus service.
I'm sorry but that official's statement does not even kinda imply race. Like it or not, bus stops and train stations accessible by everyone are hotbeds of panhandling, pickpockets, and sometimes worse. An area where people just pass through on their way to somewhere else far away, distracted and in a hurry, is a great place for criminal behavior.
If you read up on the history of public transportation in the US, you will be gobsmacked by the racism at play.
To wit: in NYC, the highway to the beach was explicitly designed with overpasses too low to accommodate buses, to keep blacks from the beaches and the white suburbs that surrounded them: http://www.hopesandfears.com/hopes/now/politics/216905-the-l...
