"Out there?" Be more specific. Explain how someone needs to uproot their whole life and family to chase jobs that may not exist by the time they get "out there." They could get out there and end up in the same position they are now, rejected by all employers in the human-resources game, and now living in a place more expensive than before. Moving to where the jobs supposedly are is easier said than done.
Maybe bachelors can afford that luxury, but it's not viable for everyone.
Large metropolitan areas usually have more available jobs than isolated, low population areas or small towns. Moving out of an economically depressed area is better than subsisting on welfare or handouts. Moving to places with better economic outlooks have what Americans (and the world's population) have done since they began recording those sorts of things.
Obviously, it's tougher for middle-aged or older people. But for younger people there's nothing to be gained by staying in an economically depressed area.
I know what it's like to lose a job you've had for a long time and have to live off your savings for a few years. I've got a lot of sympathy for people who've lost their jobs after working faithfully for a company for many years and were left in the lurch. But finding another job can be done.
