 According to the traditional Marxist account of power, domination is understood on the model of class exploitation; domination results from the capitalist appropriation of the surplus value that is produced by the workers. As many second wave feminist critics of Marx have pointed out, however, Marx’s categories are gender-blind (see, for example, Firestone 1970, Hartmann 1980, Hartsock 1983, Rubin 1976). Marx ignores the ways in which class exploitation and gender subordination are intertwined; because he focuses solely on economic production, Marx overlooks women’s reproductive labor in the home and the exploitation of this labor in capitalist modes of production. As a result of this gender-blindness, second wave Marxist or socialist feminists argued that Marx’s analysis of class domination must be supplemented with a radical feminist critique of patriarchy in order to yield a satisfactory account of women’s oppression; the resulting theory is referred to as dual systems theory (see, for example, Eisenstein 1979, Hartmann 1980). As Young describes it, “dual systems theory says that women’s oppression arises from two distinct and relatively autonomous systems. The system of male domination, most often called ‘patriarchy’, produces the specific gender oppression of women; the system of the mode of production and class relations produces the class oppression and work alienation of most women” (Young 1990b, 21). Although Young agrees with the aim of theorizing class and gender domination in a single theory, she is critical of dual systems theory on the grounds that “it allows Marxism to retain in basically unchanged form its theory of economic and social relations, on to which it merely grafts a theory of gender relations” (Young 1990b, 24). Young calls instead for a more unified theory, a truly feminist historical materialism that would offer a critique of the social totality.
