Especially since populations are potentially in decline with fertility rates below replacement rates. It seems like an existential problem for the government if they want future taxpayers.
The current belief seems to be that the future is going to need a lot fewer people.
Governments shouldn't "want" anything. If people want more taxpayers, so be it.
While technically correct for Western-aligned nations, not all governments are for the people and by the people.
The implication that Western nations are different is fairly funny. I'd argue most of the governments in Asia are doing a lot more for the people than many Western governments.
I am not sure that is true. Japan remains closed to economy-saving immigration, Uyghurs have atrocities committed against them, several countries losing their collective minds due to social media-induced riots/panics.
Maybe Tibet and the GenZ revolution as a counterexample?
