Many people say that they don't have the option to change jobs, yet when they get laid off or the factory where they work shuts down, they find a way to survive even if they have to make sacrifices to do so.
FWIW, people living in poor rural areas, the rust belt, Reservations, etc. are surviving, true, but doing so in conditions that aren't quite first-world.
People for whom the American dream of a car for everyone has left them stuck in one place when they can't afford that car. People that need an expensive car because it's the only way to get to their far-flung job, or get groceries, or go a doctor's appointment? Where even if there's a bus, it only runs a few times a day and may require long transfers to go across town.
