We're in Trump times - we're in the time this misogynist hate clown is the leader of the free world, and when Putin has made abusing your wife legal, and transgender bathrooms have just been disallowed in school. There are all these political setbacks. And there's no question that those setbacks are very real and need to be treated as civil-rights issues.

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.

The more money women make, the less violence, the less sexual crimes against women. Everything horrific and misogynistic declines. But then what you're dealing with here is "What does it mean to be in love with people who are your equals?" And that's a very beautiful thing that we should cherish, but it's also incredibly tough in some ways.

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

Women become breadwinners, men become caregivers. That's the birth of intimate marriage.

Men are not taking women's job, which are good jobs. Being a nurse is an excellent job.

The division [between how much housework men and women do] is declining across all advanced economies - not for the reasons that people want, which is men are doing more, but because women are doing less of it, but even then, the trend is getting towards equality.
