CHAPTER XXV.
THE GENERAL LAW OF CAPITALIST ACCUMULATION.
In this chapter we consider the influence of the growth of capital on the lot of the labouring class. The most important factor in this inquiry, is the composition of capital and the changes it undergoes in the course of the process of accumulation.
The composition of capital is to be understood in a two-fold sense. On the side of value, it is determined by the proportion in which it is divided into constant capital or value of the means of production, and variable capital or value of labour-power, the sum total of wages. On the side of material, as it functions in the process of production, all capital is divided into means of production and living labour-power. This latter composition is determined by the relation between the mass of the means of production employed, on the one hand, and the mass of labour necessary for their employment on the other. I call the former the value-composition, the latter the technical composition of capital. Between the two there is a strict correlation. To express this, I call the value-composition of capital, in so far as it is determined by its technical composition and mirrors the changes of the latter, the organic composition of capital. Wherever I refer to the composition of capital, without further qualification, its organic composition is always understood.
The many individual capitals invested in a particular branch of production have, one with another, more or less different compositions. The average of their individual compositions gives us the composition of the total capital in this branch of production. Lastly, the average of these
