Have you ever read the sci-fi short story 'The Marching Morons'
Never heard of it.

quite late in life, while less intelligent people had many children
and started early in life.
I'm not sure I would agree with this. There are some fairly intelligent poor people who have many children, while there are some fairly unintelligent rick people who only have a few children.

I agree, although I don't know if there are any specific gene that is more prevalent among poor people, except possible skin colour, Africa being poorer than the rest of the world, and mostly, well African.
This is countered somewhat by the fact that the infant death rate in Africa is pretty high. How this compares to India and China I don't know.
