Because poor people often live together with our poor people and rely on each other, and the question of "why don't you, your partner, your parents who help you look after your children, and everyone else don't just get a job in the same area that won't pay much less than what all of you are getting now?" has many answers. One is that minimum wage falling way, way below living wage ensures that the employers can always pay lower for even low-paying jobs. Another is that perverse zoning laws often don't allow people to work where they live.
