The old lie is that aging societies need foreign-workers to support the social-welfare scheme, but that is just a facile theory with many unproven factors to it. I saw an interesting article from a German paper - and I am trying to relocate it. It pointed out that in the early 1980's, Germany had something like 2 million Turks, and 1.5 million were working. Now Germany has 4+ million Turks, and how many are working? Still 1.5 million.
Really?
That doesn’t seem at all plausible. I’d be very interested if you could provide a link to this article
