What I am arguing here through the words of Mandel is not simplyt hat capitalist development is geographically uneven, for some geographical unevenness is the result of every social process. The key point is that capitalism- or if one prefers, the normal activity of profit-seeking capitalists- intrinsically builds upon regional or spatial inequalities as a necessary means for its continued survival. The very existence of capitalism presupposes the sustaining presence and vital instrumentality of geographically uneven development. What is it that becomes geographically differentiatied? The list begins with rates of profit, a crucial parameter, but also includes the organic composition of capital, labour productivity, wage rates, the costs of materials necessary for the reproduction of labour power, levels of technology and mechanization, the organization of labour, and the incidence of class struggle. These differentials are maintained through geographically and sectorally uneven allocations of capital investment and social infrastructure, the locational concentration of centers of control over labour and the means of production, the interlocking circuits of capital in the urbanization process, and the particular forms of articulation between capitalist and non-capitalist reltaions of production. All form part of the complex and distinctive spatialization that has marked the historical development of capitalism from its origins
