Sexual liberation is a fabulous thing – in some ways. But it can also turn men into louts, because women don’t expect much in return for access. Today, most men can have all the sex they want for very little cost – no fancy dinner required. The irony, as Mr. Regnerus writes, is that today’s mating market is probably more dominated by men’s interests than ever before.

When women complain that marriageable men (sober, steady good providers) are harder to find than ever, they may well be right. The marriage rate is falling steadily, especially among the lower middle class, while long-term stable marriage is increasingly a privilege reserved for the better off.

A lot of women seem to have their act together these days. But a lot of men don’t.
