I have absolutely no idea how any country with below-replacement birthrates and an ageing population can argue against immigration, yet still expect the benefits that labour provides, like food availability, trades, and medical care. If we were using a system that prioritised essential jobs over pandering to the rich, then maybe, but instead we have capitalism. (And I know, I know... blaming the immigrants is a way to mislead people so they don't blame the ultra-wealthy, but still...)
