I think that is hyperbole, but I agree with your general take.
Maybe we are just at the top of the human population sigmoid curve and this is a normal collective correction. We've hit the carrying capacity of the post-industrialized world. Food isn't the limiter as much as an unconscious 'perceived opportunity for growth'.
Like we could not imagine a fairer distribution that would incentivize more people to have children in a positive fashion.
I think we might even go the other direction - circumscribe the rights of women directly to increase the birth rate, Handmaids Tale style.
Given recent events, I think the Republic of Gilead will be a real thing in the USA before too long.
Here in Japan, it's much better: all medical expenses for children are free. Daycare is still a problem though, but the cost isn't nearly as awful as in America, however availability is a real problem.
The real costs add up in the 40 hour work week. School, daycare, and even the legal frameworks those operate in are intended for at least one parent to live close to the child and work at most part time.
By and large millennials in the US were the first generation where both parents were raised to work for a variety of good reasons. How many jobs really let parents cut out at 4 to commute home for a 5pm pickup?
Now consider the childcare and opportunity costs of raising children.
That's an American problem because of its car culture. In better societies, there's public transit, and/or cities/towns are walkable, so kids can just walk home by themselves. Here in Japan, kids are far more independent and have no trouble getting themselves to and from school, even with non-working parents.
What a baffling comment to post under an article about the birth rate of a specific country and quite different from that of many others.
Understand, we are complex beings. The desire to reproduce is not conscious. It is innate and compulsive. And if you interfere with that hormonally derived urge, this is the result.
It's not about money. That's on the conscious side. People had scads of kids during depressions and recessions, even when the pill was available, having kids was more important than not.
And if you looka around the world, the amount of children has nothing to do with the country, or culture. Women oppressed or not, it doesn't matter.
And what culture is more unique than Japan compared to the West? It's not culture, for the entire planet has a collapse in birthrates.
We're going extinct.
