It is in the mode just described, that those countries which formerly supplied Europe with manufactures, but which owed their power of doing so not to any natural and permanent advantages, but to their more advanced state of civilization as compared with other countries, have lost their pre-eminence as other countries successively attained an equal degree of civilization. Lombardy and Flanders, in the middle ages, produced some descriptions of clothing and ornament for all Europe: Holland, at a much later period, supplied ships, and almost all articles which came in ships, to most other parts of the world. All these countries have probably at this moment a much larger amount of capital than ever they had, but having been undersold by other countries, they have lost by far the greater part of the share which they had engrossed to themselves of the benefit which the world derives from commerce; and their capital yields to them in consequence a smaller proportional return. We are aware that other causes have contributed to the same effect, but we cannot doubt that this is a principal one. As much as is really true of the great returns alleged to have been made to capital during the last war, must have arisen from a similar cause. Our exclusive command of the sea excluded from the market all by whom we should have been undersold. The adoption by France, Russia, the Netherlands, and the United States, of a more severely restrictive commercial policy, subsequently to 1815, has done great injury undoubtedly to those countries; for the duties which they have established are intended to be, and really are, of the class termed _protecting_; that is to say, such as force the production of commodities by more costly processes at home, instead of suffering them to be imported from abroad. But these duties, though chiefly injurious to the countries imposing them, have also been highly injurious to England. By diminishing her exportation, or preventing it from increasing as it would otherwise have done, they have kept up the prices of all imported commodities in England, above what those prices would have fallen to if trade had been left free.
