of the community, but also by the varying price of food and other necessaries, on which the wages of labour are expended?
In the same country double the quantity of labour may be required to produce a given quantity of food and necessaries at one time, that may be necessary at another, and a distant time; yet the labourer's reward may possibly be very little diminished. If the labourer's wages at the former period, were a certain quantity of food and necessaries, he probably could not have subsisted if that quantity had been reduced. Food and necessaries in this case will have risen 100 per cent. if estimated by the quantity of labour necessary to their production, while they will scarcely have increased in value, if measured by the quantity of labour for which they will exchange.
The same remark may be made respecting two or more countries. In America and Poland, a year's labour will produce much more corn than in England. Now, supposing all other necessaries to be equally cheap in those three countries, would it not be a great mistake to conclude, that the quantity of corn awarded to the labourer, would in each country be in proportion to the facility of production?
If the shoes and clothing of the labourer, could, by improvements in machinery, be produced by one fourth of the labour now necessary to their production, they would probably fall 75 per cent.; but so far is it from being true, that the labourer would thereby be enabled permanently to consume four coats, or four pair of shoes, instead of one, that his wages would in no long time be adjusted by the effects of competition, and the stimulus to population, to the new value of the necessaries on which they were expended. If these improvements extended to all the objects of the labourer's consumption, we should find him probably at the end of a very few years, in possession of only a small, if any, addition to his enjoyments, although the exchangeable value of those commodities, compared with any other commodity, in the
