Not agreeing fully with your hypothesis with regards entire peoples (China's biggest population growth spurt was in the mid-Qing, a time of affluence) but I agree to the practical reason behind poorer people having more kids than richer people.Might be because for a long time, especially in the XXth century, many countries of Asia have been extremely poor. When a country is extremely poor, it almost always encourages a population boom. It's not a paradox, it's understandable. There are many factors for this. First all the families have more kids, so that more of them can survive.
It's anyway known poor people tend to have more children. Example: gypsies in Romania have 3 times as many kids as the other people. Turks in Germany have a higher natality than Germans, etc. That's the best explanation I could come up with.![]()
For rich people an extra child = more expenses. Expensive food, clothing, a bigger house, education, perhaps even the child's marriage expenses when he/she grows up. Major dent into the parent's lifestyle. Can't have that. So :thumbdown
In contrast for poor people an extra child isn't that much trouble at all. Cheap food is about the only essential. No need for new clothes as he/she can just wear hand-me-downs. No need for extra housing space. Education? Luxury! The kids will be out helping earn a buck by the time they can walk. Such a quick ROI. Why not?

The world is full of irony.
