My experience with "hypergamy" is that the more "hypergamous" the woman, the more narcissistic they are.
Take the story of "The Fisherman and His Wife" (posted HERE). The wife wants to be God. Everything she gets is not enough. She wants More&More&More and ends up back in her hovel, poverty-stricken.
The story is essentially a retelling of the story of Adam and Eve. The "serpent" targets Eve with promises of "being like God," and she falls for it. Then a weak Adam listens to her, and they go from Paradise to our fallen world.
I've met a few wealthy men, who wives these men allow to spend and spend and spend, and the wives always wanted more. They were never satisfied and never grateful. The men were weak, like Adam.
"Hypergamous" women are better explained by the Seven Deadly Sins: greedy and lazy and envious. They covet, like Eve.
I've mentioned I read Tom Wolfe's Back to Blood a few years ago, when it first came out.
I recently reread it, and part of the novel is about a "hypergamous" woman and how she wrecks her life.
Her name was Magdalene and she was a Cuban-American, raised in what Wolfe calls a "Low Rent" district of Miama.
She's beautiful but not smart, and under Associative Mating (which is what people really do) her mate should be Hector, a Cuban-American cop who is very much in love with Magdalene and wants to marry her. (As for Hector's brainpower, let's just say he'll never make detective, and sergeant if he's lucky).
But while seeing Hector she is also involved with an rich "Anglo" doctor, so she tells Hector no. Hector of course has a fit, because he never saw it coming.
Then she deludes herself some billionaire Russian crook is interested in her. Not just interested, but fascinated.
He has sex with her one time and dumps her. She has gone from Hector to the doctor to a billionaire.
So she calls Hector, trying to get back together with him. She says something interesting: "Just as I started to feel something for him..."
What matters to her is what she feels. She has problems with boundaries, which is a problem all narcissists have.
Magdalene devalues Hector when he dumps him, she devalues the doctor, she idealizes and then devalues the Russian.
At the end Hector has already found another woman, one actually somewhat smarter then Hector, and who is good for Hector because she makes him a better man.
Magdalene ends up with no job, no boyfriend to support her, no money and no hope. Her life has turned into a living hell. And she never had any gratitude for any of these men. Her attitude was that she deserved it - was entitled to it - and they owned everything they had to her.
Magdalene's story is also a retelling of Eve.
Notice that Hector ends up with a woman who is good for him and makes him a better man.
"Hypergamous" women, being consumed by envy and covetousness and laziness, will bring down every man they get involved with.
It's a more humble, self-aware woman, who wants the man to be happy and be the best he can be - those are the ones who make the best wives.
Not a greedy, lazy, covetous, "hypergamous" woman who's imitating Eve in everything she does.
