Yes I have been poor, probably more than you, and I have chosen any job that's near to survive. Before starting my career in IT, I once had my car wrecked and consequently lost my job. I had to take another job nearby and commute by bicycle. If you talk about poor people benefiting from car centric cities, then you are delusional either about what "poor" really means, or about the reality of relying on a car when you're poor.
