2. Value.

The life and motion of capitalistic society appears as an infinite net of exchange operations, formed out of numerous entwined meshes.

Through the medium of money, men continually exchange the most varied commodities and services. A ceaseless buying and selling, an uninterrupted series of exchanges of things, and labour power—this constitutes the essential part of human relations in capitalistic society. An economic map of these relations, graphically displayed, would not be less confusing than an astronomical map which exhibited the manifold and intersected orbits of the heavenly bodies. And yet there must be some rule or law which operates in this seeming medley of movements; for men do not work or exchange their goods by hazard, like savages who give their entire lumps of gold or rough diamonds for a necklace of glass pearls. The English and French economists in the seventeenth, eighteenth, and nineteenth centuries, amongst whom Petty (1623-87), Quesnay (1694-1759), Adam Smith (1723-96), and Ricardo (1772-1823) were the most original, sought for the laws which regulated exchange operations, and their theories were designated by Marx as classical bourgeois economy. Following up their investigations, Marx declared: Every commodity, that is, every thing or good produced under [96]Capitalism and brought to the market possesses a use value and an exchange value.

The use value is the utility of the commodity to satisfy a physical or mental need of its user: a commodity without use value is not exchangeable or saleable. As use values, commodities are materially different from each other; nobody will exchange a ton of wheat for a ton of wheat of the same kind, but he will for clothes.

In what measure will commodities exchange with one another? The measure is the exchange value, and this consists in the trouble and quantity of labour which the production of a commodity costs. Equal quantities of labour are exchanged with each other on the market. As exchange values, as the embodiment of human labour, commodities are essentially equal to each other, only quantitatively are they different, as different categories of commodities embody different quantities of labour. It is obvious that the quantities of labour will not be calculated according to the working methods of the individual producers, but according to the prevailing social working methods.

If, for example, hand-weaver A requires twenty hours for the production of a piece of cloth, which in a modern factory will be produced in five hours, the cloth of the hand-weaver does not therefore possess four-fold exchange value. If hand-weaver A demands of consumer B an equivalent of twenty working hours, B answers that a similar piece of cloth can be produced in five hours, and therefore it only represents an exchange value of five working hours. Thus, according to Marx, the exchange value of a commodity consists in the quantity of socially necessary labour power which its reproduction would require.

[97]This quantity of labour is no constant factor. New inventions, improvements in labour processes, increase in the productivity of labour, etc., cause a diminution in the quantity of labour necessary for the reproduction of a commodity; its exchange value, or expressed in terms of money, its price, will therefore sink, provided that other things (demand, medium of exchange) remain equal.

Consequently, labour is the source of exchange value, and the latter is the principle which regulates exchange operations. Exchange value even measures the extent of the commodity wealth of society. Wealth may increase in volume, but decrease in value, in so far as a less quantity of socially necessary labour becomes necessary for its reproduction.

The more progressive a country is industrially and the higher the level of its civilisation, the greater is its wealth, and the smaller is the quantity of labour which must be expended on the creation of wealth. In the practical Labour politics of our times, this is expressed in higher wages and shorter working hours.

It was said above that use value is a basic condition for the exchange of the individual commodity. This does not exhaust the rôle of use value. The quantity of use value of which society has need determines the quantity of the exchange values to be created. If more commodities are required than society requires, the superfluous commodities have no exchange value, in spite of the labour that is expended on them.—("Capital" (German), Vol. III., 1, pp. 175-176.)

The complete realisation of exchange values or the social labour that is performed depends, as is seen, on the adaptation of supply to demand, and is a matter of organisation, of social direction.

[98]We have noticed that the Marxian theory of value is related to that of the classical economists, but they are by no means the same thing. Apart from some improvements and definitions which Marx made, they are distinguished by the following conceptions: In the classical theory of value, the capitalist who directs production and provides with his capital the tools and raw materials of labour, markets the finished commodity, and keeps going the processes of reproduction, appears as the only creator of value: the wage worker is only one of his means of production. In the Marxian theory of value, on the other hand, the wage worker who transforms the raw materials into commodities, or removes the raw materials to the place of production, appears as the sole creator of value. Value is only created by the worker in production, and in distribution connected therewith.

3. Wages and Labour.

The worker appears to receive wages for his work. In reality he receives wages as the equivalent for the labour power expended by him, quite in accordance with the law of value, inasmuch as he receives by way of exchange as much means of sustenance as is usual and customary to replace the labour power he has expended, just as the working horse receives as much oats and hay as are necessary to maintain it capable of work.

The capitalist and the worker exchange certain quantities of commodities in proportions determined by economic laws (means of subsistence against a quantity of the commodity, labour power, of equal value, commodity for commodity, exchange value for exchange value).

[99]As, therefore, the wages of labour signify a certain quantity of the means of subsistence, so they increase even if their money form remains unaltered with a fall in the price of the means of life, for the worker is then in the position, with his unaltered wage, to buy a greater quantity of the means of life. In the reverse case, if the prices of the means of life rise, the wages of labour fall, even if their money form remains the same as previously. This law of wages, formulated by Ricardo, was accepted by Marx, but he did not content himself with this acceptance. Ricardo regarded the capitalist world as the only possible and reasonable one, at least at the time when he wrote his "Principles," while Marx from the year 1843 adopted a critical attitude towards it, and sought to negate it. Consequently, he investigated further, and expressed himself somewhat as follows:

The capitalist theoricians believed that the wages question was disposed of when it was settled by the law of value. We know, however, that every commodity possesses not only an exchange value, but also a use value, and is bought for the sake of the latter. The use value of the commodity labour power is distinguished in a very remarkable way from the use value of all other commodities.

The use or the employment of labour power creates exchange value, and can create much more exchange value than itself possesses.
