Moving for a job has a huge social cost for most people. You leave behind everyone you know.

That might be worth it for someone who wants to forge a career or explore. But for the average person who pushes paper at a generic office? You can do that anywhere. So why not do it where everyone you know lives?

There is a trade off to never putting down roots.

There can certainly be a bigger costs as you move on especially with people who establish large local networks.
