>For EU citizens, the EU is a labor transfer union by design. These 'imported laborers' were not forced, they took their chances

No it's not that simple, other EU countries had to open their market to technologically superior Western European nations who had better quality highly skilled labor and capital.

If it was simple, labor movement - I wouldn't even be bringing this up.

>Are you seriously suggesting it is a problem foreigners are not making up the board of directors of German companies

Yes it based on the fact number of immigrants Germany has.

>As a direct neighbor of DE ( I am in NL ), DE seems to have been very generous accepting refugees. A bit too generous for some.

It's just a knee jerk reaction to their aging population.
