The Wealth of Nations_ Books 4-5 - Adam Smith [42]
The two principles being established, however, that wealth consisted in gold and silver, and that those metals could be brought into a country which had no mines only by the balance of trade, or by exporting to a greater value than it imported, it necessarily became the great object of political economy to diminish as much as possible the importation of foreign goods for home consumption, and to increase as much as possible the exportation of the produce of domestic industry. Its two great engines for enriching the country, therefore, were restraints upon importation, and encouragements to exportation.
The restraints upon importation were of two kinds.
First, restraints upon the importation of such foreign goods for home consumption as could be produced at home, from whatever country they were imported.
Secondly, restraints upon the importation of goods of almost all kinds from those particular countries with which the balance of trade was supposed to be disadvantageous.
Those different restraints consisted sometimes in high duties, and sometimes in absolute prohibitions.
Exportation was encouraged sometimes by drawbacks, sometimes by bounties, sometimes by advantageous treaties of commerce with foreign states, and sometimes by the establishment of colonies in distant countries.
Drawbacks were given upon two different occasions. When the home manufactures were subject to any duty or excise, either the whole or a part of it was frequently drawn back upon their exportation; and when foreign goods liable to a duty were imported in order to be exported again, either the whole or a part of this duty was sometimes given back upon such exportation.
Bounties were given for the encouragement either of some beginning manufactures, or of such sorts of industry of other kinds as were supposed to deserve particular favour.
By advantageous treaties of commerce, particular privileges were procured in some foreign state for the goods and merchants of the country, beyond what were granted to those of other countries.
By the establishment of colonies in distant countries, not only particular privileges, but a monopoly was frequently procured for the goods and merchants of the country which established them.
The two sorts of restraints upon importation above-mentioned, together with these four encouragements to exportation, constitute the six principal means by which the commercial system proposes to increase the quantity of gold and silver in any country by turning the balance of trade in its favour. I shall consider each of them in a particular chapter, and without taking much further notice of their supposed tendency to bring money into the country, I shall examine chiefly what are likely to be the effects of each of them upon the annual produce of its industry. According as they tend either to increase or diminish the value of this annual produce, they must evidently tend either to increase or diminish the real wealth and revenue of the country.
CHAPTER II
OF RESTRAINTS UPON THE IMPORTATION FROM
FOREIGN COUNTRIES OF SUCH GOODS AS CAN BE
PRODUCED AT HOME
BY restraining, either by high duties or by absolute prohibitions, the importation of such goods from foreign countries as can be produced at home, the monopoly of the home market is more or less secured to the domestic industry employed in producing them. Thus the prohibition of importing either live cattle or salt provisions from foreign countries secures to the graziers of Great Britain the monopoly of the home market for butcher’s meat. The high duties upon the importation of corn, which in times of moderate plenty amount to a prohibition, give a like advantage to the growers of that commodity. The prohibition of the importation of foreign woollens is equally favourable to the woollen manufacturers. The silk manufacture, though altogether employed upon foreign materials, has lately obtained the same advantage. The linen manufacture has not yet obtained it, but is making great strides towards it. Many other sorts of manufacturers have, in
