You are thinking in far more modern terms than anything evolutionarily distant enough to affect this issue in a large portion of the population.
Additionally, even if you were looking to predict selection many generations in the future; modern reproduction happens at higher rates the lower in economic disparity you go, so clearly that isn’t the case.
I was responding to the sweeping statement you made about what natural selection can select for, and it can absolutely select for these sorts of advantages. It will play out differently depending on environmental factors such as economic and other disparities but this just becomes a matter of which strategy is chosen to adapt to that landscape.
Can you give an example of evolution selecting for parental survival past the maturity of progeny? I’m curious about this because I’ve never heard of a species that has that trait.
I never said it is selecting for parental survival. I was responding to "Evolution can't select for anything that happens significantly past the birth of your progeny."
The point is that there many valuable things that parents can pass on after the birth of their children that will increase their chances of success in future generations.
