An essay in the Atlantic by Anne-Marie Slaughter in the summer of 2012 raised many perplexing issues about the roles of women in America. It challenged some of the established concepts that came out of the Women’s Liberation Movement of the 1960s and ’70s and made it clear that nothing is clear about the roles of women today.

Ironically, at about the same time that Slaughter was telling women they cannot have all they might want in both their personal and professional lives, Sheryl Sandberg of Facebook and Marissa Mayer of Yahoo were telling women that they should aspire to the corner offices and positions of leadership, almost without exception.
