the starting point of reproduction in a capitalist system. The first condition of reproduction for the capitalist producer is thus seen to be a successful realisation of the commodities produced during the preceding period of production. Now we come to a second important point. Under a system of private economy, it is the individual producer who determines the volume of reproduction at his discretion. His main incentive is appropriation of surplus value, indeed an appropriation increasing as rapidly as possible. An accelerated appropriation of surplus value, however, necessitates an increased production of capital to generate this surplus value. Here a large-scale enterprise enjoys advantages over a small one in every respect. In fine, the capitalist method of production furnishes not only a permanent incentive to reproduction in general, but also a motive for its expansion, for reproduction on an ever larger scale. Nor is that all. Capitalist methods of production do more than awaken in the capitalist this thirst for surplus value whereby he is impelled to ceaseless expansion of reproduction. Expansion becomes in truth a coercive law, an economic condition of existence for the individual capitalist. Under the rule of competition, cheapness of commodities is the most important weapon of the individual capitalist in his struggle for a place in the market. Now all methods of reducing the cost of commodity production permanently amount in the end to an expansion of production; excepting those only which aim at a specific increase of the rate of surplus value by measures such as wage-cutting or lengthening the hours of work. As for these latter devices, they are as such likely to encounter many obstacles. In this respect, a large enterprise invariably enjoys advantages of every kind over a small or medium concern. They may range from a saving in premises or instruments, in the application of more efficient means of production, in extensive replacement of manual labour by machinery, down to a speedy exploitation of a favourable turn of the market so as to acquire raw materials cheaply. Within very wide limits, these advantages increase in direct proportion to the expansion of the enterprise. Thus, as soon as a few capitalist enterprises have been enlarged, competition itself forces all others to expand likewise. Expansion becomes a condition of existence. A growing tendency towards reproduction at a progressively increasing scale thus ensues, which spreads automatically like a tidal wave over ever larger surfaces of reproduction.
