I wanted to point out a really good article related to this post, namely about women "choosing" to leave the workplace. It says,
On a variety of basic policies—including parental leave, family sick leave, early childhood education, national childcare standards, afterschool programs, and health care that’s not tied to a single all-consuming job—the U.S. lags behind almost every developed nation. How far behind? Out of 168 countries surveyed by Jody Heymann, who teaches at both the Harvard School of Public Health and McGill University, the U.S. is one of only five without mandatory paid maternity leave—along with Lesotho, Liberia, Papua New Guinea, and Swaziland.
The article is entitled, "The Opt-Out Myth."
