People like me get extremely confused when economists/politicians continually stress the imperative of importing millions of people from third world countries to stabilize the populations and economies of first world nations, when exactly the same economists/politicians talk about how robots are going to be replacing the jobs that these immigrants are supposed to fill. Any basic demographic arithmetic will show that the numbers involved in these decisions will permanently end the people of Germany, Sweden, etc. whose national identities have stood for hundreds of years, and whose common histories go back thousands. To what end!?
