When Ann-Marie Slaughter got the opportunity to work in her dream in Washington, D.C., she took it, and commuted back and forth from her home in Princeton, New Jersey. She found that working long hours on someone else's schedule meant she could no longer be both the parent and the professional she wanted to be. Slaughter says the best hope for improving the lot of all women, and for closing what's been called a "new gender gap"—measured by wellness rather than wages—is to close the leadership gap: to elect a woman president and 50 women senators; to ensure that women are equally represented in the ranks of corporate executives and judicial leaders. Only when women wield power in sufficient numbers will we create a society that genuinely works for all women, Slaughter continued.
