Nor would the effect be essentially different in a country which continued to feed its own people, if instead of a demand for its raw produce, there was the same increasing demand for its manufactures. These manufactures, if from such a demand the value of their amount in foreign countries was greatly to increase, would bring back a great increase of value in return, which increase of value could not fail to increase the value of the raw produce. The demand for agricultural as well as manufactured produce would be augmented; and a considerable stimulus, though not perhaps to the same extent as in the last case, would be given to every kind of improvement on the land. A similar effect would be produced by the introduction of new machinery, and a more judicious division of labour in manufactures. It almost always happens in this case, not only that the quantity of manufactures is very greatly increased, but that the value of the whole mass is augmented, from the great extension of the demand for them, occasioned by their cheapness. We see, in consequence, that in all rich manufacturing and commercial countries, the value of manufactured and commercial products bears a very high proportion to the raw products; [10] whereas, in comparatively poor countries, without much internal trade and foreign commerce, the value of their raw produce constitutes almost the whole of their wealth. If we suppose the wages of labour so to rise with the rise of produce, as to give the labourer the same command of the means of subsistence as before, yet if he is able to purchase a greater quantity of other necessaries and conveniencies, both foreign and domestic, with the price of a given quantity of corn, he may be equally well fed, clothed, and lodged, and population may be equally encouraged, although the wages of labour may not rise so high in proportion as the price of produce. And even when the price of labour does really rise in proportion to the price of produce, which is a very rare case, and can only happen when the demand for labour precedes, or is at least quite contemporary with the demand for produce; it is so impossible that all the other outgoings in which capital is expended, should rise precisely in the same proportion, and at the same time, such as compositions for tithes, parish rates, taxes, manure, and the fixed capital accumulated under the former low prices, that a period of some continuance can scarcely fail to occur, when the difference between the price of produce and the cost of production is increased.
