I am always amazed at how some people believe they are inherently better people because of how they vote, where they live or even what TV shows they watch. Everything today is signal. Your job is a signal. Your car is a signal. Your meals are a signal. That's why Facebook consists of so many posts about what people are having for dinner or some bumper sticker mythology about the high pay of Finnish teachers.
Selling used cars to poor people does not make you better. Supporting legsilation against car dealers does.
