Adam Smith considers a wide variety of economic reforms in The Wealth of Nations, but he defends none as forcefully as international free trade. He dedicates Book IV to explaining the fatal flaw in the mercantile system, the dominant theory of political economy in 18th-century Europe: it mistakes gold and silver for true wealth. The mercantile system asks countries to focus on achieving a favorable balance of trade, or exporting more than they import, so that other countries will owe them gold and silver. But gold and silver are only valuable because people will trade them for other goods and services. For instance, Smith details how, after the Spanish discovered massive gold and silver mines in the Americas, Europeans didn’t suddenly become richer—rather, gold and silver became cheaper. Real wealth, this shows, is not gold and silver, but the ability to obtain “the necessaries and conveniences of life.” Gold and silver can typically buy this ability, but so can many other things.
Smith describes how, based on the mercantile system, European countries imposed a variety of policies to reduce imports and boost exports. This kept their existing industries alive but forced consumers to overpay for goods and slowed economic growth in the long term. In other words, the mercantile system made foreign goods more expensive in an attempt to make consumers choose marginally less expensive domestic goods and help the nation hoard gold and silver. Instead, Smith argues, in most cases European nations should just embrace free trade, buy cheap foreign goods, and invest the savings in more productive activities. Not only will this lead to a more efficient government; Smith suggests that this will also help all people in a society afford the items they need and ultimately thrive.

Mercantilism and Free Trade Quotes in The Wealth of Nations
Every man is rich or poor according to the degree in which he can afford to enjoy the necessaries, conveniencies, and amusements of human life. But after the division of labour has once thoroughly taken place, it is but a very small part of these with which a man’s own labour can supply him. The far greater part of them he must derive from the labour of other people, and he must be rich or poor according to the quantity of that labour which he can command, or which he can afford to purchase. The value of any commodity, therefore, to the person who possesses it, and who means not to use or consume it himself, but to exchange it for other commodities, is equal to the quantity of labour which it enables him to purchase or command. Labour therefore, is the real measure of the exchangeable value of all commodities.
In the course of a century or two, it is possible that new mines may be discovered, more fertile than any that have ever yet been known; and it is just equally possible, that the most fertile mine then known may be more barren than any that was wrought before the discovery of the mines of America. Whether the one or the other of those two events may happen to take place, is of very little importance to the real wealth and prosperity of the world, to the real value of the annual produce of the land and labour of mankind. Its nominal value, the quantity of gold and silver by which this annual produce could be expressed or represented, would, no doubt, be very different; but its real value, the real quantity of labour which it could purchase or command, would be precisely the same.
Political economy, considered as a branch of the science of a statesman or legislator, proposes two distinct objects; first, to provide a plentiful revenue or subsistence for the people, or, more properly, to enable them to provide such a revenue or subsistence for themselves; and, secondly, to supply the state or commonwealth with a revenue sufficient for the public services. It proposes to enrich both the people and the sovereign.
Commerce, which ought naturally to be, among nations as among individuals, a bond of union and friendship, has become the most fertile source of discord and animosity. The capricious ambition of kings and ministers has not, during the present and the preceding century, been more fatal to the repose of Europe, than the impertinent jealousy of merchants and manufacturers. The violence and injustice of the rulers of mankind is an ancient evil, for which, I am afraid, the nature of human affairs can scarce admit of a remedy: but the mean rapacity, the monopolizing spirit, of merchants and manufacturers, who neither are, nor ought to be, the rulers of mankind, though it cannot, perhaps, be corrected, may very easily be prevented from disturbing the tranquillity of anybody but themselves.
The nature of things has stamped upon corn a real value, which cannot be altered by merely altering its money price. No bounty upon exportation, no monopoly of the home market, can raise that value. The freest competition cannot lower it, Through the world in general, that value is equal to the quantity of labour which it can maintain, and in every particular place it is equal to the quantity of labour which it can maintain in the way, whether liberal, moderate, or scanty, in which labour is commonly maintained in that place. Woollen or linen cloth are not the regulating commodities by which the real value of all other commodities must be finally measured and determined; corn is. The real value of every other commodity is finally measured and determined by the proportion which its average money price bears to the average money price of corn.
The man who employs either his labour or his stock in a greater variety of ways than his situation renders necessary, can never hurt his neighbour by underselling him. He may hurt himself, and he generally does so. Jack-of-all-trades will never be rich, says the proverb. But the law ought always to trust people with the care of their own interest, as in their local situations they must generally be able to judge better of it than the legislature can do.
Consumption is the sole end and purpose of all production; and the interest of the producer ought to be attended to, only so far as it may be necessary for promoting that of the consumer. The maxim is so perfectly self-evident, that it would be absurd to attempt to prove it. But in the mercantile system, the interest of the consumer is almost constantly sacrificed to that of the producer; and it seems to consider production, and not consumption, as the ultimate end and object of all industry and commerce.
Frequently a man of great, sometimes even a man of small fortune, is willing to purchase a thousand pounds share in India stock, merely for the influence which he expects to acquire by a vote in the court of proprietors. It gives him a share, though not in the plunder, yet in the appointment of the plunderers of India. [...] About the prosperity of the great empire, in the government of which that vote gives him a share, he seldom cares at all. No other sovereigns ever were, or, from the nature of things, ever could be, so perfectly indifferent about the happiness or misery of their subjects, the improvement or waste of their dominions, the glory or disgrace of their administration, as, from irresistible moral causes, the greater part of the proprietors of such a mercantile company are, and necessarily must be.
It is not, therefore, the poverty of the colonies which occasions, in the greater part of them, the present scarcity of gold and silver money. Their great demand for active and productive stock makes it convenient for them to have as little dead stock as possible, and disposes them, upon that account, to content themselves with a cheaper, though less commodious instrument of commerce, than gold and silver. [...] In those branches of business which cannot be transacted without gold and silver money, it appears, that they can always find the necessary quantity of those metals; and if they frequently do not find it, their failure is generally the effect, not of their necessary poverty, but of their unnecessary and excessive enterprise. It is not because they are poor that their payments are irregular and uncertain, but because they are too eager to become excessively rich.
[The British Empire] has hitherto existed in imagination only. [...] It is surely now time that our rulers should either realize this golden dream, in which they have been indulging themselves, perhaps, as well as the people; or that they should awake from it themselves, and endeavour to awaken the people. If the project cannot be completed, it ought to be given up. If any of the provinces of the British empire cannot be made to contribute towards the support of the whole empire, it is surely time that Great Britain should free herself from the expense of defending those provinces in time of war, and of supporting any part of their civil or military establishment in time of peace; and endeavour to accommodate her future views and designs to the real mediocrity of her circumstances.
