"I am emphatically not suggesting that women have a preference to mate with violent abusers instead of gentle, kind, and resourceful millionaires. Given the choice, any sane woman would prefer the latter to the former. However, the process of mating is far from random or unrestricted; no woman (or man) has an entire range of potential mates to choose from. Due to the highly socially structured and constrained nature of meeting people, which results in assortative (nonrandom) mating, the choice that some women unfortunately face is often between unemployed, uneducated, unintelligent, unmotivated, alcoholic men who are violent, and unemployed, uneducated, unintelligent, unmotivated, alcoholic men who are not. My suggestion is merely that, under some circumstances, women may have been selected to prefer the former to the latter. Some (present-day) losers may be better than others, especially in the context of the ancestral environment. There is even some evidence from field experiments from four American cities that employed men are more likely to batter their wives than unemployed men."
