I mean what happens is skilled workers from poorer countries (Croatia in my case) move to richer EU countries, then we have nobody to perform construction - and now we have issued work Visas for 5% of the population basically. And you see newspaper stories of these people basically being treated like slave labor (crammed in small apartments, completely dependent on the visa provider, often abused). Just a few days ago there was another story about an immigrant worker being raped by her employer - also an immigrant that was just done serving his previous rape sentence. And plenty of stories of these people not being paid for months, documents being held, etc. The unions have no standing because theres nobody left to be a part of the union - most people already left for Germany/Switzerland/etc. So Germany is just riding on the EU migration for now - but considering population dynamics - that's a short wave.
