What stands out to me on that map is the reversal of fortunes for Spain, Greece, East Germany and Poland. It is clear that East Germany and Poland out competed the rest of Europe. It isn’t really possible to see with that map that there has been a net outflow of jobs to other parts of the world.
It’s a separate issue that businesses have used their greater leverage against people in order to extract more profitability. It’s obvious that corporate workforce mobility is a major problem for any country with a high standard of living. Unfortunately most governments don’t see that as a problem because government employees are the last ones that would become effected since government can borrow for a long time to cover their unexpected revenue shortfalls.
