Looks like the decline in eastern europe is largely due to economic reasons and people migrate torwards the west? The economic decline in eastern europe after the end of the cold war and the neoliberal privatisation as well as corruption and mismanaged in each economy is something that's not often discussed. Beeing in eastern europe feels sometimes like being in a western colony because most corporations / supermarkets / products are just western products. Also more often than not it's not the place for innovation but rather cheap labor workbenches for western corporations. Not sure if that was a given in the 90ies or wether it was the result of the politics at this time. If anyone can recommend some literature I'd be interested. For the former GDR (also big population loss due to economic reasons) one could argue that at least some industries were killed to avoid competition from western corporations but of course it's difficult to reliable connect cause and effect. Is in the EU eastern nations also this oligarch problem that ukraine/russia inflicted on themselves?
