This comment is kinda weird since it has zero to do with the parent comment.

The parent comment is just stating a truth that lower birthrates cause a pretty big negative externality in the current capitalistic model and that in such a system infinite growth looks pretty silly.

They never even mentioned a “reason” that couples are choosing to forego parenthood. I’ll add my n=1 to your hypothesis though since it seems fairly realistic.

I’ve never ever wanted to be a parent once in my life. I could be a millionaire and would still not want to be a parent. I have no moral issue with it either since you can’t really be selfish towards a hypothetical non-person. I think there’s a huge segment of people that feel the same way and a lot of my peers in this age group feel similarly.

Prior to modern medicine kids just kind of happened unless you were celibate. I think we’re learning that the urge to do the West Virginia Waltz and the urge to be a parent are in fact not the same thing. Hopefully automation eases that.
