I read the whole post. It is still wrong and non responsive. Non-breeding individuals can benefit the population that passed them the genes responsible for their inability to breed. We are not discussing mutations. We are discusing stable populations carrying genes that survive selection because the group benefits.
Yes, and that places the argument for evolution on more tenuous ground than arguments based on the passing of genetic material from one generation to the next, for there are any number of experiential or environmental factors that can mitigate the benefits of surviving selection.
