Thus capitalist production and reproduction imply a constant shifting between the place of production and the commodity market, a shuttle movement from the private office and the factory where unauthorised persons are strictly excluded, where the sovereign will of the individual capitalist is the highest law, to the commodity market where nobody sets up any laws and where neither will nor reason assert themselves. But it is this very licence and anarchy of the commodity market which brings home to the individual capitalist that he is dependent upon society, upon the entirety of its producing and consuming members. The individual capitalist may need additional means of production, additional labour and provisions for these workers in order to expand reproduction, but whether he can get what he needs depends upon factors and events beyond his control, materialising, as it were, behind his back. In order to realise his increased aggregate of products, the individual capitalist requires a larger market for his goods, but he has no control whatever over the actual increase of demand in general, or of the particular demand for his special kind of good. The conditions we have enumerated here, which all give expression to the inherent contradiction between consumption and private production and their social interconnection, are nothing new, and it is not only at the stage of reproduction that they become apparent. These conditions express the general contradiction inherent in capitalist production. They involve, however, particular difficulties as regards the process of reproduction for the following reasons. With regard to reproduction, especially expanding reproduction, the capitalist method of production not only reveals its general fundamental character, but, what is more, it shows, in the various periods of production, a definite rhythm within a continuous progression--the characteristic interplay of individual wills. From this point of view, we must inquire in a general way how it is possible for every individual capitalist to find on the market the means of production and the labour he requires for the purpose of realising the commodities he has produced, although there exists no social control whatever, no plan to harmonize production and demand. This question may be answered by saying that the capitalist's greed for surplus value, enhanced by competition, and the automatic effects of capitalist exploitation, lead to the production of every kind of commodity, including means of production, and also that a growing class of proletarianised workers becomes generally available for the purposes of capital. On the other hand, the lack of a plan in this respect shows itself in the fact that the balance between demand and supply in all spheres can be achieved only by continuous deviations, by hourly fluctuations of prices, and by periodical crises and changes of the market situation.
