Those who maintain that labour, or, as some Socialists assert, the labourer's labour, is the only source of wealth, look merely at the mechanical factor, but omit the force which directs and controls it. The Socialistic argument "We can run the mills without the capitalists, but they cannot run them without us"[157] is misleading. Labour is certainly an indispensable ingredient in production, but it is no more indispensable than is direction, invention, and thrift. Hence it is as absurd to assert "All wealth is due to labour" as to say "All wealth is due to invention," or "All wealth is due to thrift." As the brain is more important than the hand, at least in a highly organised state of production, so invention, organisation, management, and thrift are more important than manual labour, because invention, organisation, management, and thrift alone enable manual labour, working with modern machinery, to be highly productive. In fact, it may be asserted that wealth is created not so much by labour as by the saving of labour. A factory-owner who is dissatisfied with the profits of his factory or with its products does not get better workers, but gets a better manager or better machinery, keeping his workers. This fact proves that labour is the least important factor in modern production. The doctrine "Labour is the only source of wealth" is untenable and absurd.
Another fundamental doctrine of Socialism is that of
According to that law, "wages under competition can never be higher than that which will just support the labourer and enable him to renew his kind."[158] In the words of Lassalle, the inventor of the Iron Law of Wages, "the wages of the labourer are limited to the exact amount necessary to keep him alive."[159]
The British Socialist writers tell us: "The average price of wage-labour is the minimum wage--_i.e._ that quantum of the means of subsistence which is absolutely requisite to keep the labourer in bare existence."[160] "The labourer cannot as a rule command more than his cost of subsistence in return for his labour. This principle, that the return to labour is determined by the cost of subsistence of the labourer, is generally known as 'The Iron Law of Wages.' But has not this law been discarded even by some Socialists? There have been attempts in some quarters to demonstrate that this law does not actually operate with the rigidity at first claimed for it; but in truth, it stands as firmly to-day as when insisted upon by Lassalle."[161] "Capitalism always keeps the wages down to the lowest standard of subsistence which the people will accept,"[162] for "the basis of wages is the cost of subsistence of the labourer. This is called the 'Iron Law of Wages.'"[163] "By the Iron Law of Wages the recompense of the workers always tends to the minimum on which they are willing to subsist. If they are content with water to drink and cabbage to eat, they may be sure that the means of buying whisky or roast beef will very soon be taken from them. Messrs. Rentmonger, Interestmonger, and Profitmonger will speedily scent additional swag, and they will have it, too."[164] "The 'Iron Law of Wages' reduces the wages to as near the level of the means of subsistence as local circumstances will admit of."[165] If these arguments were correct it would follow that the workers could cause their wages to rise by drinking wine instead of whisky, and by smoking Havana cigars instead of pipe-tobacco.
