Is the OP trying to define hypergamy? I think the OP doesn't really understand what hypergamy is... he has his own definition, and according to HIS definition his argument makes sense. Hypergamy is nothing more than a chick's natural urge to trade up when she finds a dude that has more of what she THINKS she wants at any particular emotional moment. If she THINKS she needs money, and you have money, she will be attracted to you... BUT if another dude with MORE money comes along she will be attracted to that new man. It doesn't mean she will automatically act on that attraction because she already has time in, and an emotional attachment to the dude she is with in addition to her social conditioning, but that urge is always there... she's a chick, and she can no more change the way she is then the fact that a man is going to always be attracted to hot women.
In contrast, if a chick thinks she needs a stable middle class guy that loves kids, kittens, nature walks, and yard sales.... WELL that is what she thinks she needs.... now she would be one of a small minority of chicks, but they are out there, if she is also hot.... well, that's a unicorn and they do not exist. But if the chick thinks she needs a 'man' that vomits his feelings, loves kids, kittens, nature walks, and yard sales, and she has a man that does all this silly chick sh!t, and another dude with MONEY comes along.... she will NOT be attracted to the dude with money... because that is NOT what SHE THINKS she NEEDS.
All chicks are attracted to the same three things, Looks, Status, and Money.
LOOKS are nothing more than what a chick finds physically attractive. A majority of women find men with a great physique, masculine features, who dresses well attractive... But if she is a chick with a Santa fetish, she's going to think older fat dudes are attractive.
STATUS is nothing more than his position in any particular micro-culture, and a man's ability to add value in that micro-culture. So if a chick is a band groupie, she will always be looking for the most popular musician. If a chick is religious.... she'll be interested more in the Pastor of a church than the Deacon. It all depends on what micro-culture the chick is interested in.
MONEY is really the only thing that is universal, but it is important to understand that even this is based on a chick's needs. At some point having more money doesn't really help you that much. If you have sufficient resources to meet her needs, and another dude comes along with more money than she thinks she needs, it will have a lessor effect on her level of attraction, and other the other factors, status and looks will be more of a factor. If she wants a millionaire, and you have $10 million, another dude with $15 million isn't going to trigger her hypergamous instincts.
Here is the confusing part of all this as you try to understand women... what she is attracted to will CHANGE based on where her emotions are in any given moment. This is why LTRs end in most cases. When she says "We grew apart, and it's not you it's me." Well that is the true, but reading between the lines what she really means is this "You are no longer meeting my emotional needs because what I think I need has changed, and regrettably you are no longer meeting those needs, and since my SMV is changing quickly, I have an opportunity to trade up while I still have something to trade."
The bottom line is if you want to make a relationship work with a chick, you have to fvcking pay attention to her changing needs and take steps to match her new wants and needs without becoming a simp... which is not easy, but the fact that there are about 20% marriages are relatively happy, it can be done. You will increase your chances of pulling this off if you do a good job of screening out chicks that want what you don't have, and are willing to compromise and just accept a chick that is just attractive enough to turn you on.
