Probably most men have not heard the term hypergamy. Yet it is something that affects men’s lives greatly. Moreover, it affects most men’s lives negatively. Even the men who see its effects in a positive light are in the long term negatively impacted. Furthermore, women are truly victims also (real victims, not manufactured for the news media victims). This all rather seems like the plague. Actually, it is probably worse. The plague comes and the survivors pass on immunity to successor generations. Unleashed hypergamy creates misery for generation after generation after generation (approximately three generations so far).
Hypergamy, in short, is the desire for women to have sex with only the “sexiest” men. “But of course”, one might say. After all, men naturally want the most beautiful women. So, everything is equivalent, and we can all go home. Well, there is more to the story. Much more. Information that many deliberately try to ignore.
Men may want the most beautiful women, but they realize that not all men can have the very best, and are often willing to commit to one that is not top-tier. After all, men learn quickly that life is work, it can be difficult, and that compromises need to be made. From a mathematical perspective, men value women on a more or less linear scale.
Women on the other hand, really truly do want the sexiest men, and place a very high value on them. The non top-tier men are valued very little. This OKCupid study really shows this dynamic in action. Your homework is to go there and read it.
