Yeah, exactly the former DDR lands have the same problem though their issues only dates to post WWII.

Civic Platform has dismissed millions of blue-collars who lost their jobs after the state-owned companies went belly up after 1989. A small percentage of wiseguys made enormous profit but millions of people didn't really feel their economical situation got all that better. We've waited 30 years to cash in on overthrowing the communism and it's not happening. Yeah, everyone can buy a car these days but two holiday family trips to Soelden or Canary Islands per year? Hell, that's still beyond most of Pole's economical resources. Forget Canary Islands, some parents can't afford to send their kids on the Baltic shore. I was lucky enough my father's mine funded three weeks of seaside holiday in the summer for the employers' kids like me. Now it's obviously gone.
