That is NOT an accurate definition of "hypergamy."
Men, too, would like to mate with the best-available female.
But if it becomes clear that that female is not, in fact, available, then men are more flexible in lowering their standards until they find a female who is "willing."
Hypergamy does not refer to the "best available." It refers to always wanting a mate with a higher status, above-average characteristics - than one's own.
Typically, women will rate about 80% of all men as "below-average in appearance." Typically, women will demand that the man be six-foot tall (automatically excluding about 90% of all men). Typically, women will demand that the man earn much more than they, themselves do.
THAT is hypergamy.
Regards,
You are correct. Hypergamy is all about competition among women for the same top 10% of men.
You also have women spending their teens and 20’s chasing the same “cute guys” (tall, good looking, “genetically superior” physically), then reluctantly “settling” for a guy with decent earning power in their 30’s.
Some women choose to be “single moms”, having kids by the cute guys, then looking for some hard-working shlub to marry and support them and their spawn.
