Earlier quoted context omitted.
What is the alternative? All of the “developed” nations need immigration to prevent the social systems from completely falling apart. Our entire financial system is based on increasing population growth and the young paying to support the old. There aren’t enough young people. Without immigration, pensions, healthcare, social safety nets, property values… it all implodes. We go back to 1930 where old people just die…
It is weird to hear: 1) stop having so many kids, it's bad for the Earth, and 2) we're not having enough kids, let's substitute with immigrants.
Also, isn’t immigration a negation of 1)? The kids are already born, they’re just not in the same country.
Sarcasm aside, there are two systemic problems at play. 1) is ecological, and 2) is economic. The second may be physically easier to solve- but it still requires us to figure out a way to move beyond our capitalist system that a) prioritizes relentless growth and consumption, and b) has countries with large welfare programs that requires new workers and taxpayers to keep the elderly and the ill off the streets.
