America has a complicated relationship with motherhood. Our country constantly talks about how important moms are, but at the same time it rarely follows it up with actual help. In fact, we tend to penalize mothers in the workplace. And now there's evidence that the so-called "motherhood penalty" can even hurt women who aren't mothers and never intend to be.
The evolution of women's rights has propelled tens of millions of bright and talented women into the workforce over the past several decades -- a very good thing. But there have also been unintended consequences, among them a dramatic surge in the number of women who do not have children, whether by choice or happenstance.
