It treats hypothetical males as selfish animals who only care about dating a physically attractive fertile female and hypothetical females as selfish animals who only care about dating a socially attractive tribal chieftain!

I tried going further than that by making them exactly symmetrical: both sexes want a physically fit partner who wears nice clothes.

At any rate, my argument holds no matter what men/women want. As long as men and women can invest scarce resources into improving their dating value.
