This BS should stop (even if you vote for AfD or National front)
It is so difficult we still to get a working visa into Western EU. The way this is done is by total bureaucratic nature of Ausländerbehörde.
When he was CTO from Netflix, Gaurav Agarwal Could not get a visa to relocate to Germany. (No more with Netflix)
So even of one has > €80K salary and working in Apple or MS hq in Munich it is pain in the arse.
On the other hand this is encouraging people to apply and get passports. I for one would have never naturalised as German if the residence permit was quick and easy.
In summary, there are encouraging people to migrate.
Then EU citizens should support undocumented immigrants, as we do in the US. It is inhumane not to give them full welfare.
