See, for example, this argument by Becker: “The responsibility of married women for childcare and other housework has major implications for earnings and occupational differences between men and women, even aside from the effect on the labor force participation of married women. I submit that this is an important reason why the earnings of married women typically are considerably below those of married men, and why substantial occupational segregation persists.” Becker, A Treatise on the Family, p. 78.
