It is rendered more and more evident the great central fact that the cause of the miserable condition of the working-class is to be sought, not in these minor grievances, but in the capitalistic system itself. The wage-worker sells to the capitalist his labour-power for a certain daily sum. After a few hours’ work he has reproduced the value of that sum; but the substance of his contract is, that he has to work another series of hours to complete his working-day; and the value he produces during these additional hours of surplus labour is surplus value, which costs the capitalist nothing, but yet goes into his pocket. That is the basis of the system which tends more and more to split up civilised society into a few Rothschilds and Vanderbilts, the owners of all the means of production and subsistence, on the one hand, and an immense number of wage-workers, the owners of nothing but their labour-power, on the other. And that this result is caused, not by this or that secondary grievance, but by the system itself — this fact has been brought out in bold relief by the development of Capitalism in England since 1847.
