This model focuses on classes of people and their relationship to other classes, or to society in general. These two concepts are incompatible. Affirmative action flies in the face of equal treatment under the law. And that is a right for which women have fought, and fought hard, for centuries. When Susan B. Anthony and Elizabeth Cady Stanton battled to have women explicitly mentioned in the Constitution, it was in order to secure equal treatment under the law.
Affirmative action does nothing for women whose goal is legal equality.
Affirmative action aims at socioeconomic equality. It calls for distributive justice. This referred to institutional arrangements that excluded or hindered certain classes of people from participating in the distribution of power. Institutional discrimination is not the same as personal prejudice. For example, a company might decide to hire people from its community out of a sense of local pride.
