At a certain level, capitalist development thus has the tendency to impede its own progress. These obstacles are ultimately due to the fact that progressive labour productivity, involving the severance of the immediate producer from the means of production, does not benefit society as a whole, but only the individual entrepreneur; and the mass of labour power and men-hours which has been 'set free' by this process becomes redundant and thus is not only lost to society but will become a burden to it. The real wants of the masses can only be satisfied more fully in so far as there can be an ascendancy of a 'populist' mode of production based upon the union between the producer and his means of production. It is the aim of capitalism, however, to gain possession of just these spheres of production, and to destroy in the process the main factor which makes for its own prosperity. The periodical famines in India, for instance, recurring at intervals of ten or eleven years, were thus among the causes of periodical industrial crises in England. Any nation that sets out on capitalist development will sooner or later come up against these contradictions inherent in this mode of production. And the later a nation embarks on the capitalist venture, the more strongly will these contradictions make themselves felt, since, once the home market has been saturated, no substitute can be found, the outside market having already been conquered by the older competing countries. The upshot of it all is that the limits of capitalism are set by the increasing poverty born of its own development, by the increasing number of redundant workers deficient in all purchasing power. Increasing labour productivity which can rapidly satisfy every effective demand of society corresponds to the increasing incapacity of ever broader masses of the population to satisfy their most vital needs; on the one hand, a glut of goods that cannot be sold--and on the other, large masses who lack the bare necessities.
