a long discussion of various factors, but the big one is this:
The noted public-policy scholar Anne-Marie Slaughter, in a book called Unfinished Business, singled out what she calls the “care penalty” as a main driver of gender inequity.
Here’s how Slaughter sees it:
ANNE-MARIE SLAUGHTER: If you take women who don’t have caregiving obligations, they’re almost equal with men. It’s somewhere in the 95 percent range. But when women then have children, or again are caring for their own parents or other sick family members who need care, then they need to work differently.
