DPRK-pop? I don't know if I want to know what the fuck is that

I suppose you are from Spain, so you can freely work anywhere in the UE. Germany, for example, is way richer than Spain, companies up there pay way more than the ones in the south. If your argument about free immigration is correct, millions and millions of Italians, Greeks, Spaniards.. .are already living in Germany or the Netherlands, right?
