In order to analyse the processes underlying the sickly state of modern capitalism, it is important to understand some of the basic concepts of Marxist economics. This lesson starts with the concepts of ‘commodities’ – goods or services produced for sale on the capitalist market, and ‘value’ - determined by the ‘socially necessary labour time’ required for their production.
Capitalism’s driving motive is to create capital – wealth generated through the exploitation of workers - by making profit. Each company is concerned with its own profits. To make that profit it creates ‘commodities’ – goods or services produced for sale only. These each have a [qualitative] ‘use value’, in other words they are useful to those who buy them because of their physical properties. This is different to the [quantitative] ‘exchange value’, in the Marxist sense. The capitalists are interested in what they can sell things for – exchanging the commodities they produce for money, making profit and accumulating capital.
Driven by that motive, they developed the mass production of goods, achieving economies of scale through concentrating many workers in one factory, and greater efficiency due to the development of machinery and through division of labour in the workforce. Rather than making a whole product from start to finish, workers are often reduced to small repetitive tasks on a part of a future product – parts which, in a global market, can be manufactured in different countries.
The thing that the creation of all commodities has in common is human labour, ‘by hand or by brain’. All natural resources must be worked on to realise their value. Minerals must be dug up and extracted from rock; wood has to be felled from trees. At each stage of production, from mining to smelting, milling or refining, manufacture and distribution, more labour is added, and more value is therefore added to each commodity.
But what gives each commodity its distinct value? Karl Marx explained that one commodity’s value in relation to another can be boiled down to the average units of labour contained in each. All commodities take a particular time to make. However much prices fluctuate, a car will always cost more than a child’s scooter – because a car takes a longer time to manufacture.
However, the amount of labour time that goes into each commodity will also depend on the level of machinery and technique available to make it. Obviously, if one worker takes longer to make an identical object to someone else, it does not give it more value! Similarly, a car produced on an outdated production line isn’t going to be more valuable than an identical one produced more quickly using the latest available technology. So, to be more accurate, the value of a commodity is dependent on the average time required to produce it under normal production conditions, the ‘socially necessary labour time’. If, in one company, work is being done less efficiently, for whatever reason, then the firm risks becoming uncompetitive and in the longer term can go out of business.
A similar threat faces nation states with a lower ‘productivity of labour’ than their global competitors! For example, according to the Confederation of British Industry, productivity in the British economy (as measured by output per worker) is projected to be 24% below the pre-2008 financial crisis trajectory, by the last quarter of 2027. That leaves the British economy vulnerable in a coming world recession.
As a final point to consider, if new technology results in a general increase in productivity, of course that means more commodities can now be produced in the same amount of time. As long as there is a big enough market for this increased output, potentially a greater amount of wealth is created when the commodities are sold. However, at the same time, the value of each individual commodity will fall, because the socially necessary labour time in each one reduces.
