The alternative to taking in immigrants is to shrink demographically, as Japan is doing and as Germany was doing before the recent change in immigration policy. Urban educated people don’t want a house full of children usually, and so the Japanese are not replacing themselves, and nor would Americans without immigration. A big shrinkage of the population of the sort in which Japan is engaged is an unprecedented social experiment. Who will support the growing ranks of the elderly and retired? Who will build new buildings? What will happen to property prices as houses and schools empty out? Who will serve in the military? Who will invent new technology? Wouldn’t the country become weak economically and militarily and perhaps prey for a younger, more dynamic neighbor? And, no, Trump, Norway is not going to save you from all that. Salvadoran Americans might, if you let them.
Andrew Bolt ran the argument that we are “full” that we can’t afford immigrants from “shithole” countries as well.
