When I came to Harvard, there were no tenured women except one, who was in a chair reserved for a woman. It's still an uphill battle, and I encountered great sexism in parts of my career, but I have to say that things are a lot better than they used to be. There are many women today doing wonderful work all over the academy.

Life is about more than earning a living, and if you're not in the habit of thinking about it, you can end up middle-aged or even older and shocked to realize that your life seems empty.

If you really do want to increase women's status, you could focus on just that, but you'd probably better focus also on women's education. Access to artificial contraception, I would say, is also a very important determinant of women's status.
