Hypergamy is a commonly discussed, yet often misunderstood concept. Women are conditioned to seek their peer value mates during young age (16-30) and then are unable to unlearn that conditioning later on. While in her prime, she is at the very peak of the sexual hierarchy for the simple fact that most other women on the planet are either to young or old to compete against her. Men of all age on the other hand desire women in their prime years, thus creating a demand side that is bigger than the supply side. The female supply side therefore gains negotiating power for the brief window in time where she is part of the prime year fertile minority.

I took the liberty coloring the 2017 census sheet of the US trying to illustrate what I mean.

Compare this sheet to how hypergamy is commonly pictured. This way of looking at it ignores the fact that the female side is significantly smaller than the male side.

Taking only the yellow and green sections into account gives us about 100m men competing for 45m women. By default the women already outperform the men. For those around TRP getting mad about hypergamy: why should she settle for some no good chump if she already has the market leverage to select for the better half of men? Now subtract all women from this equation that men are usually not attracted to and the advantage gets higher and higher.

Selecting the top percentage of men is only natural if you are part of the top percentage of women.

tl;dr: Hypergamy is not a malicious concept but a natural reaction the SMP ratios of available desirable mates of both genders.
