i mean yeah, this is true, but one thing that you have to be careful of as a society, especially when you have a significant population, is keeping your general population swing balanced. If 80% of one generation has kids, and then 50% of those kids have kids, That original generation is going to be a significant burden on society, purely because they outnumber the working class of the society.

Fewer children would definitely have that knock on effect, but what i still see being a significant problem is the social incentive for people to have kids. And when you have a society that is generally not conducive to having children, people are going to be less likely to have children. That's not a bad thing i suppose, but i don't think it's safe to rely on people who do want to have children, regardless.

Just to be clear here, anti-natalism is the belief that humanity as a whole, should collectively stop having children, as the lack of suffering would outweigh gained positive experience. It has almost nothing to do with this conversation, other than being an extreme side, much like forcing women to get pregnant and have children, would also be an extreme.

And i also never said that infertility wasn't an issue, i just think it's probably less pressing than building a society that people want to have children in.
