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.
