It isn’t in the near future - it is now. I’m surprised Germany wants Muslims because they welcome EU workers from member states with high unemployment. They have requirements (language & skills) that many EU citizens can’t meet, but they MUST be closer than the Muslims. Then again, by refusing other EU citizens, they are probably preventing an accelerated collapse of those countries (Portugal, Spain, Italy, Ireland, Greece).
All those countries have population dearths too. This year in Spain, for the first time, deaths exceeded births.
