I've sat through a university lecture on sexual selection (a su-theory within the Theory of Evolution), in a biology course, lectured by a woman with an advanced degree in biology.
So, I get what Dr. Peterson is saying in this very short video below pertaining to sexual selection (which has been studied by scientists).
Although, as I recall what I learned, statistically some men have like 100 wives, some 5, some 2, most 1 wife, and then lots of men that have zero (also in terms of sexual female mates period).
The research found that almost all women have 1 male mate.
The research is pretty clear in its conclusions: women are very choosy and more so than men.
Basically, this is a sexual issue that is essentially the same as the economic issue between the Republican and Democrats respective stories. Except, pertaining to the economic issue the Republicans are correct, all American poor men can be middle-class and rich, and far easier than male low on the social/hierarchy totem pole getting chosen by women.
(The social/hierarchy rankings are relative to ones culture, as in inner-city American women favor unemployed, violent, criminal men over working poor men.)
In terms of sexual selection, the life and odds of women are analogous to the wealth distribution in the Scandinavian countries. The life and odds of men are analogous to the wealth distribution of Brazil.
Men are not very discriminating, unless the go higher and higher up the hierarchy totem pole, then they will still usually sleep with "frumpy" women if its freely offered but they become extremely picky about who they choose as a wife.
