Will they do this? No, because it would require thinking outside of the box too much and would be seen as too extreme.

That still won’t work. There is no develooed country on the planet eg Sweden, Australia etc thay does not have a less then replacement birthrate. When given agency outside of a patarchial and/or religious society, most women will choose 0,1 or 2 kids, all below replacement.

For every women choosing 0 you need another choosing 5 just to tread water. That Japans and Koreas are less again may be work related but it would still be less then replacement, no matter yours, or any other suggestion.

None of this is a probelm, it’s just differnt.

Growing the population is just kicking the can down the road because you can’t grow it forever anyway… We already have a over strained biosphere; pollution, resource depletion, climate change, accelerated species extinction etc

This entire thing is a nothing burger.
