Do any of you work for your city/region's public transit? Buses, subway, etc. Could be as an operator or any position in the agency.

I have frequently thought about joining my region's subway agency in some sort of position because I have ridden it every day for many years, and really appreciate how it has allowed me to not need to deal with car ownership. However, I cannot get over thinking about how by working for the agency, I would be complicit in helping/allowing for the transportation of all the scum and pieces of shit who use the system (usually illegally by fare jumping) like homeless, drug addicts, criminals, and other groups who get onto the system and make the experience negative for actual well-to-do riders.
