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.

I changed jobs (twice) to move closer to home. I used to have a job with a 45 - 60 minute car commute (the train was over 2 hours due to the need to make 2 connections), then took a job that was only about 10 miles away (just under an hour by bike, 12 - 30 minutes by car depending on traffic). I took a bit of a pay cut for that job, but it was worth it for saving about an hour/day commuting.
Then I moved to a job that was 2 miles away (10 minutes by bike or by car). My job also happens to be close to shops, restaurants, etc -- everything I need for daily living. And I get around 1.5 hours/day of my life back compared to when I had the original, longer commute.
But I didn't just "happen" to end up living where I don't need a car, I actively sought it out.
