This theory has less to do with innate traits and more to do with social position. When there’s big social change, the people who were on the top of the old order are bound to cling to the old ways. The people who were on the bottom are bound to experience a burst of energy. They’re going to explore their new surroundings more enthusiastically.

Rosin reports from working-class Alabama. The women she meets are flooding into new jobs and new opportunities — going back to college, pursuing new careers. The men are waiting around for the jobs that left and are never coming back. They are strangely immune to new options. In the Auburn-Opelika region, the median female income is 140 percent of the median male income.

Rosin also reports from college campuses where women are pioneering new social arrangements. The usual story is that men are exploiting the new campus hookup culture in order to get plenty of sex without romantic commitments. Rosin argues that, in fact, women support the hookup culture. It allows them to have sex and fun without any time-consuming distractions from their careers. Like new immigrants, women are desperate to rise, and they embrace social and sexual rules that give them the freedom to focus on their professional lives.

Rosin is not saying that women are winners in a global gender war or that they are doing super simply because men are doing worse. She’s just saying women are adapting to today’s economy more flexibly and resiliently than men. There’s a lot of evidence to support her case.

A study by the National Federation of Independent Business found that small businesses owned by women outperformed male-owned small businesses during the last recession. In finance, women who switch firms are more likely to see their performance improve, whereas men are more likely to see theirs decline. There’s even evidence that women are better able to adjust to divorce. Today, more women than men see their incomes rise by 25 percent after a marital breakup.

Forty years ago, men and women adhered to certain ideologies, what it meant to be a man or a woman. Young women today, Rosin argues, are more like clean slates, having abandoned both feminist and prefeminist preconceptions. Men still adhere to the masculinity rules, which limits their vision and their movement.

If she’s right, then men will have to be less like Achilles, imposing their will on the world, and more like Odysseus, the crafty, many-sided sojourner. They’ll have to acknowledge that they are strangers in a strange land.
