In 1975, which was the height of the women's movement, I thought I'd write a book on women's history. But in searching for a topic, I realized that there were few places in history where men and women interacted. Finally, it hit me: 'Oh, look at the family. That's the one place.'

There is no denying that we have made great progress toward gender equality.

Feminism insists on women's right to make choices - about whether to marry, whether to have children, whether to combine work and family or to focus on one over the other. It also urges men and women to share the joys and burdens of family life and calls on society to place a higher priority on supporting caregiving work.

Feminism needs a political program because gender inequality has been fostered by political decisions.

For physical goods, there are costs associated with logistics and lead times, owing to inventories and poor forecasts of the market. With digital capital-intensive technology, however, production will inevitably move toward the final market, wherever it is. This re-localization constitutes a major shift in the structure of global supply networks.
