people looking after their own children are:
1. providing good child care
2. adding value

Don’t you think that a PhD in their thirties would add more value if they instead focused on their studies subject?
So it is not enough just for people with high IQ to have many children.
The adult needs to follow their passion/dream/work to develop the intelligence and contribute back to the society.
Smart people having more kids is not the full solution, but it is a part of the solution, and a neglected one. People already talk about improving education a lot. But it seems that education can only go so far -- some children get better results unschooled than other children get in schools.
Caring for her own children, she would instill her values as they grow. Her children would most likely get a love of knowledge and a determination to accomplish long-term tasks. Since she can produce many children, the number of people with these values experiences exponential growth from generation to generation.
If she instead outsources love to an immigrant from the third world, that other person will instill third-world values in the children. The likelihood of the children taking after their mother is greatly reduced, down only to any influence of DNA. The culture is not passed on. When fewer than two of the children take after the mother, there is an exponential decline.
In general, your direct impact on the world in nothing compared to the impact that your children can have. This likely applies even to the greatest scientists, and without question it applies to a random ordinary PhD.
What does this even mean? Please elaborate your hierarchy of cultures and their “values.” What about all the wildly successful and educated children of immigrants from these countries who are in the US now?
If you're doing anything with your life right now that isn't full-time child-rearing, then you don't really believe what you said.
Yes. This world would benefit from having less kids, no doubt. Also less helicopter parents and more science.
