Reversed trends.

Stephanie Coontz neatly sums up an old theory:

The main reason that educated and high-achieving women have trouble finding or keeping mates, according to observers past and present, is that they won't play dumb enough to assuage a man's ego or act submissive enough to put up with unfair treatment.

And notes the new trend:

[C]ollege graduates and high-earning women are now more likely to marry than women with less education and lower earnings....

The same holds for high-earning women....

[C]ollege-educated couples have lower divorce rates than any other educational group....

Educated men and women are more likely to marry and less likely to divorce than others. And guess what? They have better sex lives, too.
