'Consumption,' Bulgakov says, 'the satisfaction of social needs, is but an incidental moment in the circulation of capital. The volume of production is determined by the volume of capital, and not by the amount of social requirements. Not alone that the development of production is unaccompanied by a growth in consumption--the two are mutually antagonistic. Capitalist production knows no other than effective consumption, but only such persons who draw either surplus value or labour wages can be effective consumers, and their purchasing power strictly corresponds to the amount of those revenues. Yet we have seen that the fundamental evolutionary laws of capitalist production tend, despite the absolute increase, to diminish the relative size of variable capital as well as of the capitalists' consumption fund. We can say, then, _that the development of production diminishes consumption_.[307] The conditions of production and of consumption are thus in conflict. Production cannot and does not expand to further consumption. Expansion, however, is an inherent fundamental law of capitalist production and confronts every individual capitalist in the form of a stern command to compete. This contradiction is negligible in view of the fact that expanding production as such represents a market for additional products. "Inherent contradictions are resolved by an extension of the outlying fields of production."'[308] (Bulgakov here quotes a saying of Marx which he has thoroughly misunderstood; we shall later have occasion to deal with it once more.) 'It has just been shown how this is possible.' (A reference to the analysis of the diagram of enlarged reproduction.) 'Evidently, the greater share of the expansion is apportioned to Department I, to the production, that is to say, of constant capital, and only a (relatively) smaller part to Department II which produces commodities for immediate consumption. This change in the relations of the two departments shows well enough what part is played by consumption in a capitalist society, and it indicates where we should expect to find the most important demand for capitalist commodities.'[309] 'Even within the narrow limits of the profit motive and the crises, even on this strait and narrow path, capitalist production is capable of unlimited expansion, irrespective of, and even despite, a decrease in consumption. The Russian literature frequently points out that in view of diminishing consumption a considerable increase of capitalist production is impossible without external markets, but this is due to a wrong evaluation of the part played by consumption in a capitalist society, the failure to appreciate that consumption is not the ultimate end of capitalist production. Capitalist production does not exist by the grace of an increase in consumption but because of an extension of the outlying fields of production which in fact constitute the market for capitalist products.
