Nyaaah, when will people understand? No one in the rich and powerful and tech circles cares about people. We're "human resource" and always have been, one more mineral to be strip-mined until exhaustion (cf. South Korea) or obsolence (cf. echbros' AI wet dreams). Once gone or too hard to mine, the drilling ops move on to another quarry just like with minerals (offshoring).
High fertility in the West is bad because the American and European human mines are capital-intensive while the global South still has billions of units laying bare on the ground. "Pronatalism" is only about the top of pyramid and the narrow slice just below it - white, educated, well-mannered, elegant, artistically minded and creative societe who perpetuate the imaginary, self-proclaimed "western culture". Shame they are also those who are too worried to have lots of kids in this economy and climate, but oh well.
