The Wealth of Nations_ Books 4-5 - Adam Smith [72]
The same act, which, in the drawback upon all wines, except French wines, thus favoured the colonies so much more than other countries; in those upon the greater part of other commodities favoured them much less. Upon the exportation of the greater part of commodities to other countries, half the old subsidy was drawn back. But this law enacted that no part of that duty should be drawn back upon the exportation to the colonies of any commodities, of the growth or manufacture either of Europe or the East Indies, except wines, white callicoes, and muslins.
Drawbacks were, perhaps, originally granted for the encouragement of the carrying trade, which, as the freight of the ships is frequently paid by foreigners in money, was supposed to be peculiarly fitted for bringing gold and silver into the country. But though the carrying trade certainly deserves no peculiar encouragement, though the motive of the institution was perhaps abundantly foolish, the institution itself seems reasonable enough. Such drawbacks cannot force into this trade a greater share of the capital of the country than what would have gone to it of its own accord had there been no duties upon importation. They only prevent its being excluded altogether by those duties.
The carrying trade, though it deserves no preference, ought not to be precluded, but to be left free like all other trades. It is a necessary resource for those capitals which cannot find employment either in the agriculture or in the manufactures of the country, either in its home trade or in its foreign trade of consumption.
The revenue of the customs, instead of suffering, profits from such drawbacks by that part of the duty which is retained. If the whole duties had been retained, the foreign goods upon which they are paid could seldom have been exported, nor consequently imported, for want of a market. The duties, therefore, of which a part is retained would never have been paid.
These reasons seem sufficiently to justify drawbacks, and would justify them, though the whole duties, whether upon the produce of domestic industry, or upon foreign goods, were always drawn back upon exportation. The revenue of excise would in this case, indeed, suffer a little, and that of the customs a good deal more; but the natural
