  Chodorow's work is controversial, but it is undeniable that girls and boys grow up facing different expectations of how they will behave. Children receive strong cultural messages — from parents, teachers, peers and the media — about sex-appropriate traits and behaviors. Girls are supposed to be nurturing, self-sacrificing, non-aggressive and attractive; “care” is largely seen as a feminine characteristic. These traits traditionally contribute to women's inequality: nurturers are not seen as good leaders. There are few women CEOs, generals, or political leaders. Girls may also become disadvantaged by the anticipation of marriage and child-rearing, insofar as they are less likely than boys to invest in their human “capital”.
