You cannot have an advanced economy while holding women back from the workplace.

The research points pretty clearly to the rise of companionate marriage, and I just think it's going to keep being popular, for the very simple reason that it's basically the only way to afford a family life in the 21st-century in advanced economies. It's one of the major reasons for the spike in income inequality. Surgeons used to marry their secretaries. Now they marry other surgeons.

To me, there's two definitions of feminism. One is that you believe that women are equal human beings; that's not really a philosophy, it's just obvious. And the other is that you're actually fighting for women: you're promoting women and working towards the betterment of women.

Men's gender problems cause them a lot of suffering. There is a massive spiking suicide rate in middle age for men and a cultural attitude to male friendship that is destructive.

Marriage is this black box which is the key to all social and political problems; the family is the unit.

When you ask single men in their 20s, "Do you want children?" they want children more than women do. Again, economics drive this. If you're a 29-year-old woman, having a baby is going to seriously blow up your career. If you're a 29-year-old man, it isn't.

You have two things happening: You have the cultural and economic reality of men falling apart and traditional masculinity falling apart.
