The Wealth of Nations_ Books 4-5 - Adam Smith [119]
While Great Britain encourages in America the manufactures of pig and bar iron, by exempting them from duties to which the like commodities are subject when imported from any other country, she imposes an absolute prohibition upon the erection of steel furnaces and slitmills in any of her American plantations. She will not suffer her colonists to work in those more refined manufactures even for their own consumption; but insists upon their purchasing of her merchants and manufacturers all goods of this kind which they have occasion for.
She prohibits the exportation from one province to another by water, and even the carriage by land upon horseback or in a cart, of hats, of wools and woollen goods, of the produce of America; a regulation which effectually prevents the establishment of any manufacture of such commodities for distant sale, and confines the industry of her colonists in this way to such coarse and household manufactures as a private family commonly makes for its own use or for that of some of its neighbours in the same province.
To prohibit a great people, however, from making all that they can of every part of their own produce, or from employing their stock and industry in the way that they judge most advantageous to themselves, is a manifest violation of the most sacred rights of mankind. Unjust, however, as such prohibitions may be, they have not hitherto been very hurtful to the colonies. Land is still so cheap, and, consequently, labour so dear among them, that they can import from the mother country almost all the more refined or more advanced manufactures cheaper than they could make them for themselves. Though they had not, therefore, been prohibited from establishing such manufactures, yet in their present state of improvement a regard to their own interest would, probably, have prevented them from doing so. In their present state of improvement those prohibitions, perhaps, without cramping their industry, or restraining it from any employment to which it would have gone of its own accord, are only impertinent badges of slavery imposed upon them, without any sufficient reason, by the groundless jealousy of the merchants and manufacturers of the mother country. In a more advanced state they might be really oppressive and insupportable.
Great Britain too, as she confines to her own market some of the most important productions of the colonies, so in compensation she gives to some of them an advantage in that market, sometimes by imposing higher duties upon the like productions when imported from other countries, and sometimes by giving bounties upon their importation from the colonies. In the first way she gives an advantage in the home market to the sugar, tobacco, and iron of her own colonies, and in the second to their raw silk, to their hemp and flax, to their indigo, to their naval stores, and to their building timber. This second way of encouraging the colony produce by bounties upon importation, is, so far as I have been able to learn, peculiar to Great Britain. The first is not. Portugal does not content herself with imposing higher duties upon the importation of tobacco from any other country, but prohibits it under the severest penalties.
With regard to the importation of goods from Europe, England has likewise dealt more liberally with her colonies than any other nation.
Great Britain allows a part, almost always the half, generally a larger portion, and sometimes the whole of the duty which is paid upon the importation of foreign goods, to be drawn back upon their exportation to any foreign country. No independent foreign country, it was easy to foresee, would receive them if they came to it loaded with the heavy duties to which almost all foreign goods are subjected on their importation into Great Britain. Unless, therefore, some part of those duties was drawn back upon exportation, there was an end of the carrying trade; a trade so much favoured by the mercantile system.
