Part Three: The Production of Absolute Surplus-Value
Chapter 7 – The Labour Process and the Valorisation Process
This chapter looks at production from two points of view:
The production of use-values, without regard to the social relations within which that production takes place & the production of value.
The capitalist labour process is a combination of the production of use-values and of the production of value and surplus-value.
The main point is to show that the source of SV lies in the difference between the value of labour-power and the value created in the course of the working day.
It may only take half a day to produce the worker’s means of subsistence, but he can work for a full day. This is the source of SV.
Thus the ‘contradiction’ is resolved: SV is created without violating the laws of commodity exchange.
The distinction between labour process and valorisation process is a fundamental one.
It is the unity of the two that constitutes the capitalist production process: the production of use-values dominated by the production of SV.
Thus in a capitalist society it is only insofar as the production process produces SV that it will be undertaken by the capitalist: the production of use-values is conditional on the production of SV.
Chapter 8 – Constant Capital and Variable Capital
This chapter introduces the important concepts of constant and variable capital.
Marx argues that the value of the product is made up of the value added by the worker, on the one hand, and the value transferred from the means of production to the product.
This division corresponds to the division between abstract labour (the expenditure of socially necessary labour-time) and concrete labour (the production of a specific product by a specific kind of labour).
Constant capital is “that part of capital…which is turned into means of production (and) does not undergo any quantitative alteration in value in the process of production”
Variable capital is “that part of capital which is turned into labour-power and does undergo an alteration of value in the process of production” (p. 317)
For Marx capital is not simply the means of production.
Capital is a sum of money (value) laid out on means of production and labour power.
Labour-power has the unique property of creating value anew as it is used up.
Chapter 9 – The Rate of Surplus-Value
This chapter introduces the concept of the rate of SV (rate of exploitation).
Although the whole capital advanced appears to increase in the valorisation process, it is in fact only the variable part that increases.
The ratio of SV to total capital advanced is the rate of profit = SV/(VC + CC)
The rate of SV is “the ratio of the SV to the variable capital” (p. 324) = SV/VC
This is the same thing as the ratio of surplus labour (the labour time spent beyond that sufficient to replace the value of the worker’s labour-power) to necessary labour (the labour time spent replacing the value of labour-power, i.e. the number of hours socially necessary to produce the means of subsistence)
Thus SV simply represents a portion of the worker’s labour-time.
Chapter 10 – The Working Day
Marx argues that the length of the working day is set within limits of the necessary labour-time (the minimum) and physiological and social maximum that can be sustained.
The capitalist class demands as much as possible, the worker demands a shorter working day.
Thus between these limits it is a struggle between capital and labour, the capitalist class and the working class, that determines the length of the working day.
Marx argues that it is only when production is for exchange-value that the “boundless thirst for surplus labour arises” because before this the demand for surplus labour is limited by the needs of the exploiting class (p. 345)
Marx points to the tendency for capital to lengthen the working day as much as possible, far beyond the limits of endurance of the worker so that the labour force is debilitated.
He notes that this happens although it might seem to be in the interests of the capitalist to limit the exploitation of labour so as not to undermine the strength and numbers of the labour force in the future, but in fact capital does nothing because of overpopulation, which constantly provides new workers, and because competition between capitalists imposes such practices on every capitalist if he is to compete.
Thus it is the class struggle that determines the length of the working day.
Chapter 11 – The Rate and Mass of Surplus-Value
Marx establishes that the total mass of SV produced is equal to the variable capital advanced multiplied by the rate of SV (p. 418) – SV=VC.sv
There are limits to the extent to which capital can compensate for a reduction in the VC advanced (by employing fewer workers) by an increase in the rate of exploitation (by the lengthening of the working day) (p. 420)
If the value of labour-power and the rate of exploitation are fixed, then the mass of SV produced is proportional to the VC advanced (p. 421)
“This law clearly contradicts all experience based on immediate appearances” (since in practice capitals receive profit in proportion to the total capital laid out – the rate of profit).
Resolving this apparent contradiction Marx postpones to Volume III.
To be a capitalist it is necessary to have a certain minimum quantity of money that can serve as capital (i.e. enough to bring back sufficient SV to live on the labour of others) (p. 422)
As capital takes command of production, the capitalist directs the labour of the worker, and the capital relation becomes a coercive one.
The machine becomes the master of the worker (p. 425)
