Sure, that's why you move from one place with a decent job market to another with a decent job market. But people an aggregate move towards places that offer economic opportunity and away from those that don't -- hence the waves of migration from rural to urban areas and away from dying cities like Detroit. The only people (not quite that absolute, but close enough) who move from a place with plentiful opportunity to one without opportunity are those who a) have no choice (or feel they have no choice) -- be it due to being priced out or having to take care of an aging parent; or b) aren't subject to such economic pressures (work remotely or are financially independent).
