> They move back to where they came from, especially if there's a family support structure there. This is a big deal for workers with families and closer-to-median income. Having to pay $20,000-$30,000/yr to replace services you're getting for free from family (child care, help with home improvement/repair projects, help with transportation, all kinds of stuff) might not be that big a deal to a family making $300,000, but it's huge to a family making $70,000. A 20% increase in income made possible by moving away from family might make good sense for the former, but be break-even at best for the latter (and a losing proposition of CoL is otherwise higher than where they are).
