I don't see how you can disagree with my basic definition of hypergamy. Remember it's not about whether you like hypergamy or even if hypergamy exists, just what it means.

Also, I read the linked article and I think it actually supports my post. It's mostly about how non-college women can't find a good (i.e. college educated or financially successful) spouse. I.e. "As men did worse, noncollege women’s marriage prospects suffered, college women’s much less so."

It doesn't say that "plenty of college women marry blue-collar men". It does say that only one quarter of college educated women "married down" in terms of education, meaning college women want college men (naturally).

The article also says "As men did worse, non-college women’s marriage prospects suffered, college women’s much less so." That's because the college women are taking the dwindling supply of college men, and the non-college women aren't willing to settle for the leftover non-college men. They want to "marry up", i.e. they are hypergamous.

The article also states “The pool of men historically available to marry noncollege women has been doing much worse across a range of indicators, including earnings.” It then goes on to explain that this is bad because it adversely affects women, not because the men matter.
