The accuracy of these important statements of fact is confirmed on every hand. Committees of British spinners and weavers have repeatedly visited the United States, and then reported to their fellows at home, that wages, all things considered, were equal for spinners and weavers in Great Britain and the United States, and in some cases and respects higher in the former. Many times before his late lamented death, John Bright publicly testified that wages in England during his parliamentary life had risen in general 50%, and in some of the manufacturing lines 100%. A few months before these statements of Chadwick were made, Sir Richard Temple reported to his section of the British Association, "_That the average earnings per head in the United Kingdom, taking the whole population without division into classes, is £35, 4s., and exceeds the average of the United States, which is £27, 4s., and of Canada, which is £26, 18s., and of the Continent, which is £18, 1s.; while it falls below that of Australia, which is £43, 4s. per head._" According to this, the average earnings in Great Britain per head of the population are 30% higher than in the United States, and 81% higher than on the Continent of Europe. Truly, Britain is a prosperous and profitable country so far as average earnings of the whole people by the year is concerned. Sir Richard goes on in the same statistical paper to show, that the average annual profit on British Capital is 14%, and that Capital yields about the same rate for the United States. Now, can we easily give the grounds on which the introduction of more and better machinery, instead of displacing laborers, tends to lift and actually does lift the wages of those concerned, who continue to work with their hands and heads? We will try it. (a) It takes the hands and heads of laborers to invent and construct and keep in repair the machinery itself, that is often supposed to displace laborers, and so far forth opens a vent for the more profitable employment of some of the laborers, who before performed the cruder and more repetitive and automatic parts of the processes, which parts alone machinery can be made to perform. (b) Machinery always lessens the cost of a given amount of production, otherwise there would be no motive for its introduction. But, other things being equal, the lessened cost of a commodity broadens the market for its sale. The cheaper a useful commodity is offered, the more the buyers of it the world over. The more and the better the machinery brought in, the more and the cheaper the commodities produced and the broader and better the markets to be supplied; and, therefore, the more and the more skilful the hands needed to tend the machinery and to market the products.
