IV. Of Drawbacks
M
Of these encouragements what are called Drawbacks seem to be the most reasonable. To allow the merchant to draw back upon exportation, either the whole or a part of whatever excise or inland duty is imposed upon domestic industry, can never occasion the exportation of a greater quantity of goods than what would have been exported had no duty been imposed. Such encouragements do not tend to turn towards any particular employment a greater share of the capital of the country, than what would go to that employment of its own accord, but only to hinder the duty from driving away any part of that share to other employments. They tend not to overturn that balance which naturally establishes itself among all the various employments of the society; but to hinder it from being overturned by the duty. They tend not to destroy, but to preserve, what it is in most cases advantageous to preserve, the natural division and distribution of labour in the society.
The same thing may be said of the drawbacks upon the re-exportation of foreign goods imported; which in Great Britain generally amount to by much the largest part of the duty upon importation.
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 balance of industry, the natural division and distribution of labour, which is always more or less disturbed by such duties, would be more nearly re-established by such a regulation.
These reasons, however, will justify drawbacks only upon exporting goods to those countries which are altogether foreign and independent, not to those in which our merchants and manufacturers enjoy a monopoly. A drawback, for example, upon the exportation of European goods to our American colonies, will not always occasion a greater exportation than what would have taken place without it. By means of the monopoly which our merchants and manufacturers enjoy there, the same quantity might frequently, perhaps, be sent thither, though the whole duties were retained. The drawback, therefore, may frequently be pure loss to the revenue of excise and customs, without altering the state of the trade, or rendering it in any respect more extensive. How far such drawbacks can be justified, as a proper encouragement to the industry of our colonies, or how far it is advantageous to the mother-country, that they should be exempted from taxes which are paid by all the rest of their fellow-subjects, will appear hereafter when I come to treat of colonies.
Drawbacks, however, it must always be understood, are useful only in those cases in which the goods for the exportation of which they are given, are really exported to some foreign country; and not clandestinely re-imported into our own. That some drawbacks, particularly those upon tobacco, have frequently been abused in this manner, and have given occasion to many frauds equally hurtful both to the revenue and to the fair trader, is well known.
