I sometimes disagree with Fox News anchor Megyn Kelly. But this time she was right: There are no data proving that children who grow up in homes where the mother is the primary breadwinner fare any worse.

In a debate on Fox Business, her colleagues Lou Dobbs and Erik Erickson argued, in so many words, that moms working outside the home will harm children.
