Despite what TRP says, highly educated people are more likely to get married and stay married.

Men and women who did not complete high school were less likely to marry than were men and women with more education. Men who earned a bachelor’s degree were more likely to marry than men with less education.

The chance of a marriage ending in divorce was lower for people with more education, with over half of marriages of those who did not complete high school having ended in divorce compared with approximately 30 percent of marriages of college graduates.

The idea that a high status, professional man is going to marry a low class woman just because she's pretty is almost always nonsense. Most people marry within their own class.

People laugh at careerist women but when you think about it, most of them get married. RBG got married. Amy Coney Barret got married. Even Sharyl Sandberg got married. TRPillers might make fun of them but these women basically won in life. And when a highly educated, professional woman doesn't get married, it's usually by choice.

It's actually more likely for a woman to be unmarried or to become a single mom if she's lowly educated and poor.
