Yeah, this seems obvious to me. However, out of ethical concerns, it is not obvious that the solution is to stop educating people.

Perhaps just reminding would-be parents that if the educated and resilient stop reproducing, they are depriving the world of a thriving and resilient new generation. A clear directive that under-population is a growing concern and a few additional incentives for parents would go a long way too.

Taking a philosophical angle, why is it the "right" choice to serve our genes, the economy, or to create a younger generation to care for the elderly? It is not unethical to unburden oneself of those obligations today, but you can imagine a future where it is.
