The dimension of this issue that never gets air time is that we've made having kids almost completely intentional. The richer a country becomes, the more intentional having kids becomes. The dynamic we see with rich countries is that as having kids becomes more intentional, there's also the increase in reasons why people would choose to delay or forego having kids.

There are two competing factors: how much of a choice do women have and the opportunity cost of that choice?

If you look at the data, in rich countries much of the drop has been the reduction of unintentional teen pregnancies: women have better knowledge of and access to contraception, and they know that their lives will be better off from taking advantage of advanced education and building a career before having children.

Unless we’re talking about taking away the basic human right of bodily autonomy, that means that everything else must, as OP highlighted, focus on removing the negatives. This has to be done comprehensively to work: if, say, you provide free daycare but it runs 8-4, a professional parent probably isn’t going to change their estimate of the costs of having a child much at all since it’s still disruptive in ways which likely affect their long-term career trajectory. The richer the country, the more that matters: higher income is paired with higher cost of living and more opportunities which will be harder to take advantage of as a parent.

However, he specifically said "will want to have children and feel/know that their children's lives will be good ones."

But this doesn't necessarily mean being richer. For example, many people are afraid of what unchecked climate change is going to mean for kids born today. No amount of individual or country wealth is going to fix that issue.

I have kids myself, but man... I really really worry about this. I do personally know people cite climate change as one factor in having no kids (or fewer kids). Some people even think that having kids will make it worse. They're not wrong...

> How do you square those facts with your view here?

"Richer" countries generally have a higher cost of living. If you get paid twice as much but each sq ft of real estate costs 50% more, what does that do when someone with multiple kids needs 2000 sq ft instead of 750? Worse, what if you get paid twice as much but real estate costs three times as much because land owners keep lobbying for restrictive zoning to impose artificial scarcity?

Maybe it's more important that you be able to get a three bedroom to begin with than that the three bedrooms on the market have new kitchens; more important if you can't afford to send your kids to college in a country where a higher percentage of the people they're competing with in the labor market will have a degree.

The richer a country gets the more individualist you can become, is my basic theory.

Raising a kid as an atomic couple apart from extended family and community is a horrible experience for the parents. It takes a village and all that. Parenting is utterly exhausting if you are doing it alone with a partner and responsible for every waking moment of childcare.

You see this in immigrant communities in the US. The demographics with the most children universally are those with "old world" style family and community situations. More or less communal child care without the weirdo expectations that the "richer" parts of society has on parents. Parents are allowed to actually be adult human beings with real lives that are not hyper-scheduled to death. Kids tend to be more independent and "roam" between family and friends without official activities being scheduled every day for them. Ironically this typically results in more engaged parenting overall.

That's my theory at least - it's not much better than anyone else's though.

Generally, the more developed a country is, the more capitalistic it is. Capitalism inherently assigns monetary value to everything, even children, and as capitalist societies currently function children have deeply negative value. So deeply negative that it completely nullifies the higher “default” standard of quality of life that comes with life in a developed country.

Because it's not just money. It's time and money. You can have lots of money and nice things, but if you don't have time to raise your kids, you can't do it. And if you had the time, you wouldn't have the money.

People compare themselves to their perceived neighborhood in time and space, not to peasants from 5 thousand years ago.
