But in the case of human beings natural selection is overruled by ideologies. Prey nations by definition are ruled by losing ideologies .
'Overruled"? I have no idea what you mean. Obviously, ideologies spread in different ways than genes. But how does that "overrule" anything?
Also, how is it "by definition" that prey nations are "ruled by losing ideologies"? It is only "by definition" if we think of prey as "losers" and predators as "winners". Really? Are wildebeasts losers and lions winners? That's a bizarre way to think of the web of life. Besides, we don't know what ideologies will win out in the end. "Predator" (i.e. rich) nations have become less and less religious. Are we really sure that religion will "lose out"?
Natural selection is not "overruled" by anything. It is true that culture has a huge impact on both descendant-leaving-success and human well being. Culture influences natural selection -- so do lots of other things: the environment, competition from other species or within our own species, etc. But neither ideology or anything else "overrules" natural selection. Natural selection is what it is.
Of course their are reasons rich nations have reached ZPG: improved birth control; abortion rights; an economy that encourages working mothers; an ideology that recognizes the costs of exponential population growth; etc..
Still, ideologies, like genes, are largely transmitted from parents to children. I'll bet 99% of the world's Muslims had Muslim parents. If the Moslem population doubles in the next 50 years, and the Western secular and Christian population maintains ZPG -- will the Muslim ideology "lose out"?
Lions and wildebeasts are predators and prey. That does not make lions "winners" and wildebeasts "losers" in either a Darwinian sense, or in any other sense I can think of.
