As I warned nearly 10 years ago, the combination of hypergamy and the male-female imbalance at the universities is already severely reducing the ability of women to marry up.

Then consider that a portion of those men will prefer to marry women who are not college graduates. After all, most men are relatively indifferent to the educational attainment of their wives. Even if only 30 percent of men marry non-college graduates, that means a woman who graduates from college has less than a 50 percent chance of marrying up. Which, in most cases, means she will never marry.

Overeducating women is not merely dyscivic, it is dysgenic.
