[14] It will appear then, that a country possessing very considerable advantages in machinery and skill, and which may therefore be enabled to manufacture commodities with much less labour than her neighbours, may in return for such commodities, import a portion of the corn required for its consumption, even if its land were more fertile, and corn could be grown with less labour than in the country from which it was imported. Two men can both make shoes and hats, and one is superior to the other in both employments; but in making hats, he can only exceed his competitor by one-fifth or 20 per cent., and in making shoes he can excel him by one-third or 33 per cent.;--will it not be for the interest of both, that the superior man should employ himself exclusively in making shoes, and the inferior man in making hats? [15] Book V. ch. ii. [16] M. Say appears to have imbibed the general opinion on this subject. Speaking of corn, he says, "thence it results, that its price influences the price of _all_ other commodities. A farmer, a manufacturer, or a merchant, employs a certain number of workmen, who all have occasion to consume a certain quantity of corn. If the price of corn rises, he is obliged to raise, in an equal proportion, the price of his productions." Vol. i. p. 255. [17] M. Say says, that "the tax, added to the price of a commodity, raises its price. Every increase in the price of a commodity, necessarily reduces the number of those who are able to purchase it, or at least the quantity they will consume of it." This is by no means a necessary consequence. I do not believe, that if bread were taxed, the consumption of bread would be diminished, more than if cloth, wine, or soap, were taxed. [18] The following remark of the same author appears to me equally erroneous: "When a high duty is laid on cotton, the production of all those goods, of which cotton is the basis, is diminished. If the total value added to cotton in its various manufactures, in a particular country, amounted to 100 millions of francs per annum, and the effect of the tax was, to diminish the consumption one half, then the tax would deprive that country every year of 50 millions of francs, in addition to the sum received by government."
