But every rise in wages gained by the workmen, unless springing from or in conjunction with an increase in efficiency, will tell against themselves; it must increase the price of the article, whether houses, wheat, or boots; this must diminish the demand for the article, and this must throw some of the workmen out of employ. It is difficult to find an example of price of wages which presents any difficulty of explanation when we apply to it the consideration of efficiency. If bricklayers were to offer to exert themselves to the utmost, and do in eight hours the same amount and quality of work they now do in nine, the speculative builders would doubtless be willing to give the same wages for eight hours' work that they now give for nine. In case the labourers by increase in their efficiency are able to get higher wages, the choice will (in general) lie with them how much of the increase they take in increased money wages, how much they take in shortened hours of labour. We thus see how, in an uncivilised community, owing to the inefficiency of their labour, their whole time and energies are expended on their hunting, or otherwise providing bare subsistence. The greater skill of our civilised labourers, working with machines provided by our science, and profiting by our fixed capital (as our railway tunnels and embankments), is vastly more efficient: it ensures the labourers a certainty and regularity of food which the savage does not enjoy, and provides him a certain margin of leisure beyond what the inefficient savage labourer can count upon; it also provides the whole surplus production out of which the intellectual and leisure classes are supported. It is to be noted that an increase of efficiency in any industry (and very largely in the case of industries producing generally essential utilities) raises real wages in all other industries, and this, whether the particular trade gains (as we have seen it nearly always do) or loses, as is conceivable, though rarely occurring. Thus, if the introduction of a boot-sewing machine lowers the price of boots 50 per cent, this can have no effect in lowering the money wages of farm labourers; and, as a matter of fact, the fall in cost of boots has sensibly improved the position of farm labourers. In the same way the superior efficiency of carriers by railway over the old road carriers has diminished the cost of coal and all articles (the bulky ones most sensibly) in all parts of England. There thus arises the instructive result that handicrafts in which there has been no improvement in the last forty years have obtained a rise of real wages (amounting in some cases to 50 per cent) by the improvements in efficiency in all the trades around them.
