> imagine the state of society when that starts happening
The state of my own personal society is my apartment costs $1000 more than it did two years ago and my food costs about 25-30% more than it did two years ago. I definitely wouldn't consider having another kid, nor would I encourage my own to have one.
Absolutely understandable, yet it also leads to a somewhat odd and undesirable reality. The problems you're talking about are ones that we inflicted upon ourselves, owing largely due to poor systems (and societies) enabling the turds of society rise to the top.
So what will the systems and societies of tomorrow look like? Every child born tomorrow is basically just a lottery roll against all people having children today. And today you have vast numbers of intelligent, educated, conscientious, and far thinking individuals are simply removing themselves from the gene pool; that lottery roll for the children of tomorrow is looking less and less pleasant.
There's this irony that the sort of mindset that might consciously make the decision to not have children is the exact sort that should be raising a family 1800s style, if we want a better world. Maybe there's just something about successful urbanization that ultimately causes societies to reboot. The Roman Empire also faced a major fertility crisis in its final years.
