That point about men not reproducing seems suspect. Do you have any more details on that claim? A society where half the free men (assuming you're not counting slaves and prisoners) can't mate sounds like a failed state, or an ingredient for war and famine.

"Average men" in Western developed nations now and "average men" over all time and cultures are not the same either. Hypergamy leading to inflated standards among women is something we often discuss. (that's helped out by birth control, no doubt)
