In the mean time, one of the principal effects of those discoveries has been, to raise the mercantile system to a degree of splendour and glory which it could never otherwise have attained to. It is the object of that system to enrich a great nation, rather by trade and manufactures than by the improvement and cultivation of land, rather by the industry of the towns than by that of the country. But in consequence of those discoveries, the commercial towns of Europe, instead of being the manufacturers and carriers for but a very small part of the world (that part of Europe which is washed by the Atlantic ocean, and the countries which lie round the Baltic and Mediterranean seas), have now become the manufacturers for the numerous and thriving cultivators of America, and the carriers, and in some respects the manufacturers too, for almost all the different nations of Asia, Africa, and America. Two new worlds have been opened to their industry, each of them much greater and more extensive than the old one, and the market of one of them growing still greater and greater every day.
The countries which possess the colonies of America, and which trade directly to the East Indies, enjoy indeed the whole show and splendour of this great commerce. Other countries, however, notwithstanding all the invidious restraints by which it is meant to exclude them, frequently enjoy a greater share of the real benefit of it. The colonies of Spain and. Portugal, for example, give more real encouragement to the industry of other countries than to that of Spain and Portugal. In the single article of linen alone, the consumption of those colonies amounts, it is said (but I do not pretend to warrant the quantity ), to more than three millions sterling a-year. But this great consumption is almost entirely supplied by France, Flanders, Holland, and Germany. Spain and Portugal furnish but a small part of it. The capital which supplies the colonies with this great quantity of linen, is annually distributed among, and furnishes a revenue to, the inhabitants of those other countries. The profits of it only are spent in Spain and Portugal, where they help to support the sumptuous profusion of the merchants of Cadiz and Lisbon.
Even the regulations by which each nation endeavours to secure to itself the exclusive trade of its own colonies, are frequently more hurtful to the countries in favour of which they are established, than to those against which they are established. The unjust oppression of the industry of other countries falls back, if I may say so, upon the heads of the oppressors, and crushes their industry more than it does that of those other countries. By those regulations, for example, the merchant of Hamburg must send the linen which he destines for the American market to London, and he must bring back from thence the tobacco which he destines for the German market; because he can neither send the one directly to America, nor bring the other directly from thence. By this restraint he is probably obliged to sell the one somewhat cheaper, and to buy the other somewhat dearer, than he otherwise might have done; and his profits are probably somewhat abridged by means of it. In this trade, however, between Hamburg and London, he certainly receives the returns of his capital much more quickly than he could possibly have done in the direct trade to America, even though we should suppose, what is by no means the case, that the payments of America were as punctual as those of London. In the trade, therefore, to which those regulations confine the merchant of Hamburg, his capital can keep in constant employment a much greater quantity of German industry than he possibly could have done in the trade from which he is excluded. Though the one employment, therefore, may to him perhaps be less profitable than the other, it cannot be less advantageous to his country. It is quite otherwise with the employment into which the monopoly naturally attracts, if I may say so, the capital of the London merchant. That employment may, perhaps, be more profitable to him than the greater part of other employments; but on account of the slowness of the returns, it cannot be more advantageous to his country.
After all the unjust attempts, therefore, of every country in Europe to engross to itself the whole advantage of the trade of its own colonies, no country has yet been able to engross to itself any thing but the expense of supporting in time of peace, and of defending in time of war, the oppressive authority which it assumes over them. The inconveniencies resulting from the possession of its colonies, every country has engrossed to itself completely. The advantages resulting from their trade, it has been obliged to share with many other countries.
At first sight, no doubt, the monopoly of the great commerce of America naturally seems to be an acquisition of the highest value. To the undiscerning eye of giddy ambition it naturally presents itself, amidst the confused scramble of politics and war, as a very dazzling object to fight for. The dazzling splendour of the object, however, the immense greatness of the commerce, is the very quality which renders the monopoly of it hurtful, or which makes one employment, in its own nature necessarily less advantageous to the country than the greater part of other employments, absorb a much greater proportion of the capital of the country than what would otherwise have gone to it.
The mercantile stock of every country, it has been shown in the second book, naturally seeks, if one may say so, the employment most advantageous to that country. If it is employed in the carrying trade, the country to which it belongs becomes the emporium of the goods of all the countries whose trade that stock carries on. But the owner of that stock necessarily wishes to dispose of as great a part of those goods as he can at home. He thereby saves himself the trouble, risk, and expense of exportation; and he will upon that account be glad to sell them at home, not only for a much smaller price, but with somewhat a smaller profit, than he might expect to make by sending them abroad. He naturally, therefore, endeavours as much as he can to turn his carrying trade into a foreign trade of consumption, If his stock, again, is employed in a foreign trade of consumption, he will, for the same reason, be glad to dispose of, at home, as great a part as he can of the home goods which he collects in order to export to some foreign market, and he will thus endeavour, as much as he can, to turn his foreign trade of consumption into a home trade. The mercantile stock of every country naturally courts in this manner the near, and shuns the distant employment: naturally courts the employment in which the returns are frequent, and shuns that in which they are distant and slow; naturally courts the employment in which it can maintain the greatest quantity of productive labour in the country to which it belongs, or in which its owner resides, and shuns that in which it can maintain there the smallest quantity. It naturally courts the employment which in ordinary cases is most advantageous, and shuns that which in ordinary cases is least advantageous to that country.
But if, in any one of those distant employments, which in ordinary cases are less advantageous to the country, the profit should happen to rise somewhat higher than what is sufficient to balance the natural preference which is given to nearer employments, this superiority of profit will draw stock from those nearer employments, till the profits of all return to their proper level. This superiority of profit, however, is a proof that, in the actual circumstances of the society, those distant employments are somewhat understocked in proportion to other employments, and that the stock of the society is not distributed in the properest manner among all the different employments carried on in it. It is a proof that something is either bought cheaper or sold dearer than it ought to be, and that some particular class of citizens is more or less oppressed, either by paying more, or by getting less than what is suitable to that equality which ought to take place, and which naturally does take place, among all the different classes of them. Though the same capital never will maintain the same quantity of productive labour in a distant as in a near employment, yet a distant employment maybe as necessary for the welfare of the society as a near one; the goods which the distant employment deals in being necessary, perhaps, for carrying on many of the nearer employments. But if the profits of those who deal in such goods are above their proper level, those goods will be sold dearer than they ought to be, or somewhat above their natural price, and all those engaged in the nearer employments will be more or less oppressed by this high price. Their interest, therefore, in this case, requires, that some stock should be withdrawn from those nearer employments, and turned towards that distant one, in order to reduce its profits to their proper level, and the price of the goods which it deals in to their natural price. In this extraordinary case, the public interest requires that some stock should be withdrawn from those employments which, in ordinary cases, are more advantageous, and turned towards one which, in ordinary cases, is less advantageous to the public; and, in this extraordinary case, the natural interests and inclinations of men coincide as exactly with the public interests as in all other ordinary cases, and lead them to withdraw stock from the near, and to turn it towards the distant employments.
