The ones that do will have kids that'll have a much better planet in a couple generations and way less road traffic. Don't count on having a retirement though.
Most governments will not tolerate a declining population, though. Expect immigration to fill the gap.
And lack of abortion services.
Certain immigration. Almost all societies unfortunately currently are classist and racist.
Letting in all willing immigrants doesn’t really make sense in context of a Western welfare state. Migrants simply need sufficient educational background to find a job, without one they are just more burden to the public sector. So it’s not always about racism or classism.
It doesn’t have to always be about either issue for the core reasoning of the way the laws are laid out to be classist and racist.
I personnally think it will get a lot worse before it gets better unfortunately.
