This advantage, however, will, perhaps, be found to be rather what may be called a relative than an absolute advantage, and to give a superiority to the country which enjoys it, rather by depressing the industry and produce of other countries, than by raising those of that particular country above what they would naturally rise to in the case of a free trade.
The tobacco of Maryland and Virginia, for example, by means of the monopoly which England enjoys of it, certainly comes cheaper to England than it can do to France to whom England commonly sells a considerable part of it. But had France and all other European countries been at all times allowed a free trade to Maryland and Virginia, the tobacco of those colonies might by this time have come cheaper than it actually does, not only to all those other countries, but likewise to England. The produce of tobacco, in consequence of a market so much more extensive than any which it has hitherto enjoyed, might, and probably would, by this time have been so much increased as to reduce the profits of a tobacco plantation to their natural level with those of a corn plantation, which it is supposed they are still somewhat above. The price of tobacco might, and probably would, by this time have fallen somewhat lower than it is at present. An equal quantity of the commodities, either of England or of those other countries, might have purchased in Maryland and Virginia a greater quantity of tobacco than it can do at present, and consequently have been sold there for so much a better price. So far as that weed, therefore, can, by its cheapness and abundance, increase the enjoyments, or augment the industry, either of England or of any other country, it would probably, in the case of a free trade, have produced both these effects in somewhat a greater degree than it can do at present. England, indeed, would not, in this case, have had any advantage over other countries. She might have bought the tobacco of her colonies somewhat cheaper, and consequently have sold some of her own commodities somewhat dearer, than she actually does; but she could neither have bought the one cheaper, nor sold the other dearer, than any other country might have done. She might, perhaps, have gained an absolute, but she would certainly have lost a relative advantage.
In order, however, to obtain this relative advantage in the colony trade, in order to execute the invidious and malignant project of excluding, as much as possible, other nations from any share in it, England, there are very probable reasons for believing, has not only sacrificed a part of the absolute advantage which she, as well as every other nation, might have derived from that trade, but has subjected herself both to an absolute and to a relative disadvantage in almost every other branch of trade.
When, by the act of navigation, England assumed to herself the monopoly of the colony trade, the foreign capitals which had before been employed in it, were necessarily withdrawn from it. The English capital, which had before carried on but a part of it, was now to carry on the whole. The capital which had before supplied the colonies with but a part of the goods which they wanted from Europe, was now all that was employed to supply them with the whole. But it could not supply them with the whole; and the goods with which it did supply them were necessarily sold very dear. The capital which had before bought but a part of the surplus produce of the colonies, was now all that was employed to buy the whole. But it could not buy the whole at any thing near the old price; and therefore, whatever it did buy, it necessarily bought very cheap. But in an employment of capital, in which the merchant sold very dear, and bought very cheap, the profit must have been very great, and much above the ordinary level of profit in other branches of trade. This superiority of profit in the colony trade could not fail to draw from other branches of trade a part of the capital which had before been employed in them. But this revulsion of capital, as it must have gradually increased the competition of capitals in the colony trade, so it must have gradually diminished that competition in all those other branches of trade; as it must have gradually lowered the profits of the one, so it must have gradually raised those of the other, till the profits of all came to a new level, different from, and somewhat higher, than that at which they had been before.
This double effect of drawing capital from all other trades, and of raising the rate of profit somewhat higher than it otherwise would have been in all trades, was not only produced by this monopoly upon its first establishment, but has continued to be produced by it ever since.
First, This monopoly has been continually drawing capital from all other trades, to be employed in that of the colonies.
Though the wealth of Great Britain has increased very much since the establishment of the act of navigation, it certainly has not increased in the same proportion as that or the colonies. But the foreign trade of every country naturally increases in proportion to its wealth, its surplus produce in proportion to its whole produce; and Great Britain having engrossed to herself almost the whole of what may be called the foreign trade of the colonies, and her capital not having increased in the same proportion as the extent of that trade, she could not carry it on without continually withdrawing from other branches of trade some part of the capital which had before been employed in them, as well as withholding from them a great deal more which would otherwise have gone to them. Since the establishment of the act of navigation, accordingly, the colony trade has been continually increasing, while many other branches of foreign trade, particularly of that to other parts of Europe, have been continually decaying. Our manufactures for foreign sale, instead of being suited, as before the act of navigation, to the neighbouring market of Europe, or to the more distant one of the countries which lie round the Mediterranean sea, have the greater part of them, been accommodated to the still more distant one of the colonies; to the market in which they have the monopoly, rather than to that in which they have many competitors. The causes of decay in other branches of foreign trade, which, by Sir Matthew Decker and other writers, have been sought for in the excess and improper mode of taxation, in the high price of labour, in the increase of luxury, etc. may all be found in the overgrowth of the colony trade. The mercantile capital of Great Britain, though very great, yet not being infinite, and though greatly increased since the act of navigation, yet not being increased in the same proportion as the colony trade, that trade could not possibly be carried on without withdrawing some part of that capital from other branches of trade, nor consequently without some decay of those other branches.
England, it must be observed, was a great trading country, her mercantile capital was very great, and likely to become still greater and greater every day, not only before the act of navigation had established the monopoly of the corn trade, but before that trade was very considerable. In the Dutch war, during the government of Cromwell, her navy was superior to that of Holland; and in that which broke out in the beginning of the reign of Charles II., it was at least equal, perhaps superior to the united navies of France and Holland. Its superiority, perhaps, would scarce appear greater in the present times, at least if the Dutch navy were to bear the same proportion to the Dutch commerce now which it did then. But this great naval power could not, in either of those wars, be owing to the act of navigation. During the first of them, the plan of that act had been but just formed; and though, before the breaking out of the second, it had been fully enacted by legal authority, yet no part of it could have had time to produce any considerable effect, and least of all that part which established the exclusive trade to the colonies. Both the colonies and their trade were inconsiderable then, in comparison of what they are how. The island of Jamaica was an unwholesome desert, little inhabited, and less cultivated. New York and New Jersey were in the possession of the Dutch, the half of St. Christopher’s in that of the French. The island of Antigua, the two Carolinas, Pennsylvania, Georgia, and Nova Scotia, were not planted. Virginia, Maryland, and New England were planted; and though they were very thriving colonies, yet there was not perhaps at that time, either in Europe or America, a single person who foresaw, or even suspected, the rapid progress which they have since made in wealth, population, and improvement. The island of Barbadoes, in short, was the only British colony of any consequence, of which the condition at that time bore any resemblance to what it is at present. The trade of the colonies, of which England, even for some time after the act of navigation, enjoyed but a part (for the act of navigation was not very strictly executed till several years after it was enacted), could not at that time be the cause of the great trade of England, nor of the great naval power which was supported by that trade. The trade which at that time supported that great naval power was the trade of Europe, and of the countries which lie round the Mediterranean sea. But the share which Great Britain at present enjoys of that trade could not support any such great naval power. Had the growing trade of the colonies been left free to all nations, whatever share of it might have fallen to Great Britain, and a very considerable share would probably have fallen to her, must have been all an addition to this great trade of which she was before in possession. In consequence of the monopoly, the increase of the colony trade has not so much occasioned an addition to the trade which Great Britain had before, as a total change in its direction.
