I just looked up the definition of hypergamy on Google. It says, "The action of marrying or forming a sexual relationship with a person of a superior sociological or educational background."

This sounds like a good thing that most folks should try and do. I'm a man and I suppose I practiced (did?) hypergamy marrying a doctor whose family is wealthier than mine.

It also makes sense that women, especially pre-women entering the workforce, were hypergamous because marrying up was the only way to make your life better since you couldn't work or get an education.

I don't see what is wrong with hypergamy.
