The determination of the value of commodities by wages, which in Adam Smith still frequently appeared side by side with its determination by labour-time, has been banned from scientific political economy since Ricardo, and nowadays survives only in vulgar economics. It is precisely the shallowest sycophants of the existing capitalist order of society who preach the determination of value by wages, and along with this, describe the profit of the capitalist likewise as a higher sort of wages, as the wages of abstinence (reward to the capitalist for not playing ducks and drakes with his capital), as the premium on risk, as the wages of management, etc. Herr Dühring differs from them only in declaring that profit is robbery. In other words, Herr Dühring bases his socialism directly on the doctrines of the worst kind of vulgar economics. And his socialism is worth just as much as this vulgar economics. They stand and fall together.
After all, it is clear that what a labourer produces and what he costs are just as much different things as what a machine produces and what it costs. The value created by a labourer in a twelve-hour working-day has nothing in common with the value of the means of subsistence which he consumes in this working-day and the period of rest that goes with it.
In these means of subsistence there may be embodied three, four or seven hours of labour-time varying with the stage of development reached in the productivity of labour. If we assume that seven hours of labour were necessary for their production, then the theory of value of vulgar economics which Herr Dühring has accepted implies that the product of twelve hours of labour has the value of the product of seven hours of labour, that twelve hours of labour are equal to seven hours of labour, or that 12=7. To put it even more plainly: A labourer working on the land, no matter under what social relationships produces in a year a certain quantity of grain, say sixty bushels of wheat. During this time he consumes a sum of values amounting of forty-five bushels of wheat. Then the sixty bushels of wheat have the same value as the forty-five bushels, and that in the same market and with other conditions remaining absolutely identical; in other words, sixty=forty-five.
And this styles itself political economy!
The whole development of human society beyond the stage of brute savagery begins on the day when the labour of the family created more products than were necessary for its maintenance on the day when a portion of labour could be devoted to the production no longer of the mere means of subsistence, but of means of production. A surplus of the product of labour over and above the costs of maintenance of the labour, and the formation and enlargement, out of this surplus, of a social production and reserve fund, was and is the basis of all social, political and intellectual progress. In history, up to the present, this fund has been the possession of a privileged class, on which also devolved along with this possession, political domination and intellectual leadership. The impending social revolution will for the first time make this social production and reserve fund -- that is, the total mass of raw materials, instruments of production and means of subsistence -- a really social fund, by depriving that privileged class of the disposal of it and transferring it to the whole of society as its common property.
Of two alternative courses, one. Either the value of commodities is determined by the costs of maintenance of the labour necessary for their production -- that is, in present-day society, by the wages. In that case each labourer receives in his wages the value of the product of his labour; and then the exploitation of the wage-earning class by the capitalist class is an impossibility. Let us assume that the costs of maintenance of a labourer in a given society can be expressed by the sum of three marks.
Then the product of a day's labour, according to the above-cited theory of the vulgar economists, has the value of three marks. Let us assume that the capitalist who employs this labourer, adds a profit to this product, a tribute of one mark, and sells it for four marks. The other capitalists do the same. But from that moment the labourer can no longer cover his daily needs with three marks, but also requires four marks for this purpose.
As all other conditions are assumed to have remained unchanged, the wages expressed in means of subsistence must remain the same, while the wages expressed in money must rise, namely, from three marks to four marks a day. What the capitalists take from the working class in the form of profit, they must give back to it in the form of wages. We are just where we were at the beginning: if wages determine value, no exploitation of the worker by the capitalist is possible. But the formation of a surplus of products is also impossible, for, on the basis of the assumption from which we started, the labourers consume just as much value as they produce. And as the capitalists produce no value, it is impossible to see how they expect to live. And if such a surplus of production over consumption, such a production and reserve fund, nevertheless exists, and exists in the hands of the capitalists, no other possible explanation remains but that the workers consume for their self-maintenance merely the value of the commodities and have handed over the commodities themselves to the capitalist for further use.
