Let's not make this thread too much about specific side discussions... but let's also not forget the full picture off immigration.
We haven't mentioned the dire need of migrants for the food and catering (housekeeping, etc) industry, as in Europe, we couldn't do without migrants.
And migrants pay into our tax and into the pension system. In times, where our predominantly white population is fading out due to lack of children, migrants step up and provide with their kids.
