Nancy Chodorow argued that one reason women are universally oppressed is that women do much more hands-on childcare than men do. One limitation of this explanation is that a. nuclear families with a domestic mother are better for social stability. b. men are less skilled at childcare, so increasing their involvement would not solve the problem. c. division of family labor by gender is not uniform across different racial-ethnic groups. d. the driving force behind apparent gender roles is actually social class.
