"Urban Post-Theory, Class and the City" Kimberly DeFazio The modern city, which is the object of my study in this paper, is the product of capitalism; it is a place of commodification-a place where workers and machines are placed together in one part of it to produce wealth which is then appropriated by the owner who lives in another part. (Pre-capitalist "cities," for the most part, operate by the economics of the "country"-they are not spaces of "commodification"-they are places with markets, not market places) Both the traditional studies that have focused on the urban aesthetic and the radical left studies that have dwelled on the city as a social space, have tried to account for the faultlines of the city by diverting attention from "class." My argument is that all other city-practices (the architecture, the urban planning, . . .) are secondary to the primary economic function of the city, and that only the orthodox Marxist theory of the city as a site of class struggle between those who own the means of production and those who must sell their labor in order survive can explain the conflicts and contradictions of the "city" and produce revolutionary praxis for their transformation. The left models of analysis have recognized the antagonistic character of the urban space and traditionally foregrounded such concepts as the "Dual City" and the "Internal Colony" to emphasize the "materiality" of urban structures of class and race, thereby connecting issues of poverty and racism to economic exploitation and arguing for the necessity of "structural" not local change. In contrast to these approaches, the contemporary post-al urban theory has conceptualized the city as a cultural site and thus marginalized its social antagonisms and the project of social transformation aimed at building cities of equality. From the work of Saskia Sassen to Mike Davis to David Harvey to Arjun Appadurai, post-al theory has concluded that, as Edward Soja argues, "the contemporary urban social order can no longer be defined effectively by such conventional and familiar modes of social stratification as the class-divided Dual City of the bourgeoisie and the proletariat" (Postmetropolis 265) and as such what is necessary is to discover the "differences" and "heterogeneity" within the existing global relations. What is posited as the "post-conventional," in other words, is a social theory which "complicates" class in order to occult the fundamental divisions of the city and its class antagonisms in the interests of capital. This paper will examine some of the dominant assumptions underlying contemporary urban studies, and their consequences for the struggle for social equality. It will argue that in response to the re-structuring of social relations under globalization, which have deepened the class divide between the rich and the poor worldwide, urban theory is in the process of changing its position in the social relations of production in order to more effectively reconcile the emerging ("urban") contradictions of global capitalism. It has done so through textualizing urban studies-treating cities as fabrics of different textures, as spaces of heterogeneity and "difference"-and in doing so has mystified economic structures of inequality by tropes of diversity, difference and hybridities. In opposition to the dissimulative "complexities" of urban post-theory, I will argue for a red urban studies based on orthodox Marxism, for which their can be no "urban justice" unless the fundamentally un-just system of capitalism is collectively transformed. In making such an argument, it will situate the work of such writers as Saskia Sassen, Edward Soja, David Harvey, Raymond Williams, in contestation with the orthodox Marxism of Marx, Engels, and Teresa Ebert, and argue for the necessity of revolutionary praxis for transforming the "city" into a society in which "the free development of each is the condition of the free development of all."
