What you're saying is that while it may be true that "on average" people tend to have less children as they get more affluent, it doesn't mean that the population will eventually peak or even slow down.
This is because it only takes one subgroup to buck the "average" behaviour and continue to keep having lots of children even as they grow more affluent and eventually that subgroup will become a majority, and then the "average" behaviour will be to have more children even if affluence increases.
I think you've identified a fatal flaw. Well done.
