Gayle Tzemach Lemmon writes at The Atlantic: “I thought of this class mismatch recently as I’ve followed the discussion surrounding Sheryl Sandberg’s upcoming book, Lean In. Suddenly, and for the first time in a while, a bunch of major news outlets are talking about working-class women. All of a sudden a media that has rarely written or cared about the issues facing the women I grew up with—single moms, working days and nights and odd jobs, often at hourly wages and with no paid maternity leave—invokes their example as a reason to challenge Sandberg’s argument about women and ambition.”
