This kind of judgement is extremely common, particularly for high-earning mothers. One 2013 study showed that 16% of Americans believed that raising a child in a family where the mother is the primary earner would have a negative effect on kids, and 59% of adults still say that children are better off when one of their parents stays at home with them. Forty-five percent of these people said it was better if the stay-at-home parent was the mother, with only 2% favouring the father.
