Here's the rub. The claim is women are now earning more than men. Successful women refuse to marry men who are less successful than they are. If more women keep earning more than men the pool of successful men will continue to shrink. Successful women will have fewer options. It's a "win"-lose prospect.
Another thing — divorced men tend to remarry; divorced women - not so much, especially if they’ve had children.
I saw a paper on the above topic some years ago — as the divorce rate has gone up, so has the rape rate.
They're more likely to end up like Condoleezza Rice. A "successful" lady who has never gotten married.
But if we want our civilization to prosperity, we shouldn't be encouraging that kind of thing.
