Moving to a different geography for a substantially higher compensation. The same phenomenon depresses compensation everywhere, so chances are most people won't be able to find compensation that's enough to keep the family going.

This part of your comment was super confusing. So much so it seems better in reverse:

>As that's very unlikely, this would depress salaries everywhere.

The unlikely is that they'd find employment that's good enough to provide for the whole household elsewhere, because all geographies would be experiencing the same pressure.
