The article asserts conclusions without demonstrating that alternative conclusions are not equally likely. One example: educated women’s uneducated husbands command higher salaries. Is it that they married someone commanding a higher salary, or did their husband secure a higher salary through their wife’s encouragement, connections, intellect, higher SES (as associated with degree attainment), etc?

And of course the assumption ringing throughout this and quite a lot of marital research that people marry for the sake of being married rather than as a result of mate selection (eg, in suggesting those thirty percent of educated women just don’t have interest in marriage as a whole rather than lacking access to preferable mates).

This is grossly misogynistic and insulting. It's the same old idea that women "just want to settle down and find a nice man" dressed up with some graphs. The author has even managed to make it about men in the end.

This entire article is laughable. Back when I was in the dating pool, I encountered a couple of women that had this mentality that they would be dating down because I don't have a degree. Unbeknownst to them, I commanded a six figure salary and it was I who would be dating down had I stuck with them and their poor worldview. This mentality needs to just stop though, the idea of "dating down" or "dating up" is just nonsense.
