In the spring of 1890, a year after the land run, a man on a quarter section of Oklahoma prairie cut sod for the walls of his house. Soon he would put the plow to the virgin grass for a crop of corn. He hauled his own water, mended his own harness, and meant to rely on no one. If he held on for five years and improved the claim, the land was his. He is the self-sufficient man of American legend, the heir of Jefferson’s yeoman, and some version of him has been admired for as long as there have been Americans. There is a certain dignity in needing little from others.
Yet the history of human prosperity is very largely the history of becoming less like him.
The farmer gave up his forge, the blacksmith his fields, and the weaver his sheep. Each surrendered a measure of independence and took on a deeper reliance on others. What began as a modest exchange of grain for iron and cloth for leather grew, over centuries, into a web of specialization that no one could have foreseen, bringing with it an abundance that no self-sufficient man, however industrious, could have produced alone.
Nearly everything that sustains our daily lives is the work of people we have never met, whose names we will never know, and whose knowledge we could never hope to possess. The food upon our tables, the roofs above our heads, and the instruments through which we communicate are products of countless individual efforts, coordinated across distances and generations in ways no single mind could comprehend. Even our Oklahoma homesteader, for all his determination to live by his own labor, broke the prairie sod with a plow fashioned by distant hands, from iron he had neither mined nor smelted. We have become so accustomed to this vast cooperation that we mistake its fruits for the ordinary furnishings of an independent life.
We grasp this easily enough when the subject is a person. No one suggests that a surgeon would be better off growing his own wheat, or that a carpenter ought to forge every nail he drives. We understand the advantages of exchange almost by instinct, and we think no worse of a man for buying nearly everything he uses.
Move from the household to the nation, however, and our intuitions turn over.
What we recognize as prudence in the affairs of individuals becomes a source of anxiety when applied to nations, where dependence upon others is regarded as weakness and self-sufficiency elevated to a measure of strength. We celebrate exports, lament imports, and speak of international commerce as though prosperity were a prize to be wrested from foreign hands. In this reversal, the man on his quarter section, whose life few of us would willingly choose for ourselves, becomes the model of economic independence for a nation of hundreds of millions.
These instincts have an old name: mercantilism.
For nearly three centuries, European kings and their ministers pursued a bewildering assortment of commercial policies that would eventually come to be known collectively as mercantilism. What they shared was a set of preoccupations: the accumulation of gold and silver, the encouragement of exports, the restriction of imports, and the direction of commerce toward the interests of the state. Trade was often conceived as rivalry among nations, with a favorable balance offering proof of success.
These ideas grew in a world where commerce, sovereignty, and war were hard to tell apart. Kingdoms fought over colonies, monopolies, and raw materials. Bullion paid for armies and fitted out fleets, and a crown’s fortunes rose and fell with its command of men and material. In such an age it was easy to confuse the wealth of a nation with the resources at its ruler’s disposal, all the more so when merchants and manufacturers were happy to present their own profits as a contribution to national glory.
Into that world, two hundred and fifty years ago this year, Adam Smith published An Inquiry into the Nature and Causes of the Wealth of Nations. Much of the book is a sustained and often withering assault on what he called the mercantile system and the thicket of restrictions and privileges that had grown up around it.
Smith found one of the system’s deepest contradictions in the affairs of an ordinary household, where the advantages of specialization and exchange were accepted almost without question. In Book IV, he gave the principle its simplest expression:
“It is the maxim of every prudent master of a family, never to attempt to make at home what it will cost him more to make than to buy.”
The tailor buys his shoes from the shoemaker, the shoemaker buys his coat from the tailor, and the farmer employs them both while he attends to his fields. None of them feels diminished by the arrangement, and none would thank a magistrate for forbidding it. Smith’s question was why the same magistrate, faced with a tailor and a shoemaker under different flags, should suppose that forbidding it made either nation richer.
Beneath the question lay a deeper confusion about what wealth is. The mercantile system encouraged statesmen to measure prosperity by the money in the treasury and the output of domestic workshops. Smith turned their attention to something humbler and more substantial: the goods a people could actually enjoy, whether they made them or traded for them. A treasury might be full while the people went hungry, just as the inhabitants of a country with little gold in its vaults might enjoy considerable abundance.
His most compact statement of the point is a single sentence:
“Consumption is the sole end and purpose of all production.”
It sounds almost too obvious to say, which is precisely why it was worth saying. Farms, mines, mills, and workshops matter because of the wants they satisfy. Labor earns its honor by what it brings into being, and employment alone, however strenuous, tells us little about the value of what has been produced. When a government compels people to buy dearer domestic goods to keep an industry afloat, it asks them to surrender part of their purchasing power for the benefit of those who run that industry.
Smith saw that honest error was only part of the system’s appeal. Merchants and manufacturers who won protection from foreign rivals could gain advantages they had not earned by pleasing customers, and they could press for those privileges in the name of the very public that would pay for them. He called them, with characteristic dryness, “by far the principal architects” of the mercantile system.
The observation has lost none of its edge. A policy sold as the engine of national prosperity can work just as well as a siphon, drawing wealth from the many toward the few. Protection may allow a manufacturer to charge higher prices and preserve returns that competition would otherwise have reduced, the expense being spread among customers who seldom notice how much each purchase costs them in lost alternatives.
That imbalance helps explain the system’s longevity. Its beneficiaries have every reason to organize, lobby, and persist, while those who finance their privileges do so through a thousand purchases, seldom knowing how much extra they pay or whom the payment serves.
Mercantilism has returned to political favor at a time when the economic case against protectionism has never been more thoroughly established. Two and a half centuries after Smith exposed its central errors, and decades after empirical research began measuring their costs, governments are once again embracing policies whose consequences are as familiar as the arguments offered in their defense.
Tariffs raise prices for domestic purchasers, distort the allocation of labor and capital, invite retaliation, and confer advantages upon the producers they shelter. Their effects differ across industries and circumstances, but the evidence against treating them as a general instrument of prosperity has accumulated for decades without exhausting the political appetite for them.
The American experience is instructive. Studying the tariffs imposed in 2018, economists Mary Amiti, Stephen Redding, and David Weinstein found that the duties were passed through to American importers and purchasers rather than absorbed by foreign exporters. They estimated that the reduction in aggregate American real income had reached roughly $1.4 billion per month by the end of that year. The disruption reached factories dependent on imported components, while retaliatory duties imposed additional costs on American exporters.
Tariffs have nonetheless returned to the center of American policy, wrapped in the old promises: restore our industry, save our jobs, and close the deficit. Rates and the countries singled out for them have changed so frequently that businesses accustomed to planning investments over years have sometimes found themselves making decisions around announcements measured in weeks or even days.
Most revealing is the renewed importance assigned to the trade balance itself. Speaking to reporters in April 2025, President Donald Trump put the matter simply: “We were losing $2 trillion a year on trade. Now we’re going to be making money.”
A trade deficit, however, is no measure of national wealth lost. It records the excess of imports over exports, matched in the broader international accounts by corresponding financial flows. Nor did the United States lose $2 trillion on trade in 2024: its recorded deficit in goods and services was about $918 billion. The economic significance of such an imbalance depends upon saving, investment, and the movement of capital, none of which can be reduced to a verdict on national prosperity. Foreign purchases of American assets may help finance productive investment, while a country with a substantial trade surplus may nevertheless suffer stagnation. To read the ledger as a scoreboard is to return to the assumptions Smith challenged in 1776.
In August 2025, the administration announced an agreement for the federal government to acquire a 9.9 percent stake in Intel, funded through previously awarded but unpaid federal grants and other authorized support. Meanwhile, the State Department’s Pax Silica initiative, launched in December 2025, has sought to coordinate investment and international partnerships around semiconductors, critical minerals, and the technologies supporting artificial intelligence.
Some of this responds to genuine concerns of national security, particularly where reliance on a hostile power could threaten access to essential technologies. Smith himself conceded that defense matters more than opulence, and on that ground he defended England’s Navigation Acts. But a genuine exception is no warrant for a general principle, least of all when the industries seeking to be classified as strategic have an interest in the outcome.
Ownership adds a further complication, one Smith’s merchants would have recognized. A government that holds shares in a company acquires an interest in its success while retaining the authority to regulate its rivals, direct subsidies, govern market access, and write the rules of competition. Intel’s agreement provides for passive ownership without board representation, a meaningful limitation on direct influence, but the institutional tension remains: the referee has bought a share of one of the teams.
Once the prosperity of a nation becomes closely associated with the fortunes of selected industries, those industries acquire a powerful claim upon public resources and political protection. Firms that once courted customers and investors have new reasons to court Washington, and the rewards of political influence may begin to rival those of serving buyers. Even officials acting without favoritism would face the difficulty of deciding which technologies and enterprises deserve support, when the knowledge required to make such judgments is scattered among those investing, producing, and purchasing in the marketplace. Modern governments possess instruments far more elaborate than royal charters and navigation laws, but their sophistication does not settle the older question of whose interests these arrangements ultimately serve.
Yet the public often welcomes the very policies whose costs it must bear.
Self-interest alone cannot explain this enthusiasm. If mercantilism’s appeal were confined to those who profit from it, the doctrine might have proved easier to resist. Its strength lies partly in the fact that its assumptions accord with feelings ordinary people hold without any expectation of personal gain.
We admire productive work and the places where a community earns its living. The opening of a factory promises employment and a future for the surrounding community, while its closing can unsettle the rhythms of work around which neighborhoods, marriages, and generations of family expectations have formed.
When a mill can no longer compete, the consequences are concrete and close at hand. Men and women lose work in which they took pride and acquired skill, families must choose between uncertain employment and leaving home, and a town built around a single industry may gradually fall quiet. The buildings that once hummed with activity fall slowly to ruin as rain enters through broken windows, mortar crumbles between bricks, and weeds push through the cracks in abandoned parking lots.
These losses deserve neither indifference nor the easy assurance that the displaced will find better work elsewhere. Economic change does not apportion its hardships according to anyone’s capacity to bear them, and the gains society enjoys over decades are little comfort to a fifty-five-year-old machinist who learns that his trade is no longer in demand.
The benefits of wider commerce are generally less conspicuous. They appear in lower prices, better goods, new enterprises, and the gradual movement of resources toward uses that may not have been anticipated when an older industry began to decline. A family free to buy its children’s clothes from whoever makes them well and cheaply may spend the savings on piano lessons, a holiday, or a down payment, without tracing that modest improvement in its circumstances to the freedom of exchange that made it possible. Nor is the economy frozen at the moment the mill closes. Some workers and resources find new uses, sometimes in industries that did not exist when the old mill was built; others may endure long periods of unemployment, while machinery designed for a vanished trade may have little value elsewhere. The wider gains from commerce are real, though neither their arrival nor their distribution is automatic.
Time, distance, and the complexity of economic life obscure the connections between these events. We see the factory close and the workers depart, but rarely follow the innumerable transactions through which others benefit from cheaper goods or newly available resources. Frédéric Bastiat made this distinction between what is seen and what is not seen a central concern of his economics, and mercantilism draws much of its appeal from our difficulty in accounting for the latter.
Smith’s earlier book, The Theory of Moral Sentiments, helps explain why this difficulty persists. In its opening pages he observed that there are principles in human nature which “interest him in the fortune of others,” and that sympathy arises through our capacity to imagine ourselves in another’s circumstances.
The displaced worker and the declining town make an immediate claim upon that faculty because we can picture their circumstances and understand something of what has been lost. The millions who pay a little less for the necessities of life are no less real, but their individual gains are modest, widely dispersed, and unlikely to command comparable attention.
There is no defect of character in this uneven sympathy, although public policy guided chiefly by it may preserve familiar activities while giving too little consideration to those obliged to bear the expense.
Mercantilism draws strength from this tendency because it locates national prosperity in achievements that can be photographed: a plant that stays open, an industry that expands, a freighter loaded with domestic goods departing for foreign customers. Higher prices and opportunities that never materialized leave fewer visible traces. Our political vocabulary reflects the same inclination. We speak of protecting industry, defending jobs, and restoring manufacturing, seldom with equal enthusiasm for the less conspicuous achievement of allowing people to purchase what they want from those who can provide it most economically. Smith’s maxim that consumption is the end of production asks us to keep the buyer in view beside the maker, a task made more difficult when the maker has a face and the buyer is one among millions.
Sympathy accounts for our response to a closed mill, but it cannot explain why the nationality of the competitor should matter so much. When a factory in Ohio fails because a rival in Tennessee makes the same goods more cheaply, the workers suffer no less, yet few people call for a tariff against Tennessee. Move the rival to Guangdong and the same loss becomes a grievance against another nation. The difference suggests that mercantilism draws upon sentiments older than our economic theories.
Human beings have always found meaning and security in belonging to a family, a faith, a language, a place, or a nation. These attachments sustain trust and mutual obligation, without which communities could hardly flourish, but they also encourage us to distinguish between those within our circle and those beyond it, particularly when outsiders appear to threaten something we value.
Commerce has the unusual power to establish productive relationships among people who share few of the sentiments we ordinarily associate with cooperation. A hardware dealer in Kansas may know nothing of the customs, beliefs, or aspirations of the manufacturer in Shenzhen who supplies him, and neither needs to feel any affection for the other. Yet each advances his own purposes by serving those of a stranger, through arrangements neither fully understands.
Smith understood how far such cooperation could reach. In the first chapter of The Wealth of Nations, he considered the woolen coat of a common day-laborer, “as coarse and rough as it may appear.” Its manufacture required the shepherd, the sorter, the comber, the spinner, the weaver, and the dyer, along with merchants and sailors who transported materials from distant places and the shipwrights and toolmakers who made that transportation possible. Without the cooperation of many thousands, Smith observed, even the poorest man in a civilized country could not be clothed as he was.
In our own day the coat has become a smartphone, and the thousands have become millions, their contributions extending across much of the globe. Most have little knowledge of the finished product to which their labor contributes, while the person holding it possesses only the faintest understanding of the skills and discoveries upon which it depends.
What makes this arrangement so extraordinary is that it coordinates these efforts without requiring the participants to share a purpose beyond the exchanges in which they engage. People who disagree about religion, politics, and almost every other matter of consequence may nevertheless find it advantageous to cooperate, and in doing so discover opportunities that would remain beyond their reach if commerce were confined to those who resembled them.
Markets extend cooperation beyond the boundaries of affection and identity, enlarging the possibilities of human life without requiring any corresponding enlargement of our sympathies. Yet our inherited loyalties continue to shape the way we perceive exchange. Among neighbors, we readily acknowledge what each party gains; when the same transaction crosses a national boundary, our attention shifts toward the relative standing of the countries involved, until an exchange undertaken for mutual benefit becomes another episode in a supposed contest between nations.
Here, perhaps, lies part of the enduring romance of national self-sufficiency. The image of a country producing everything it requires offers the familiar virtue of the homesteader enlarged to the scale of an entire people, with the added promise of freedom from the uncertainties of foreign commerce and the influence of those whose loyalties lie elsewhere.
Yet the farther the division of labor extends, the more costly it becomes for any nation to reproduce within its own borders the range of knowledge, resources, and skills upon which modern prosperity rests. The attempt may require sacrifices difficult to reconcile with the very abundance and independence it was intended to secure.
Return for a moment to the man on the prairie. He appears free of the merchants upon whom his neighbors depend, yet his livelihood rests upon the fertility of his soil, the regularity of the seasons, and the success of a single harvest; a drought or a hailstorm in July could take nearly everything he possesses. The modern household depends upon more strangers than it could ever count, but access to competing suppliers often prevents any one of them from exercising comparable power over its circumstances. A poor harvest in one region need not bring hunger to another, provided commerce can carry the produce of more fortunate places to those in need.
If independence means the capacity to pursue one’s purposes without being subject to the arbitrary will of another, then the division of labor may be among its firmest foundations. The self-sufficient man must fit his ambitions to the limits of his own abilities, devoting much of his life to securing necessities that a specialized society can provide through a fraction of the same effort. The citizen of a commercial civilization draws upon knowledge he does not possess, skills he never acquired, and productive resources he could never assemble. His time, which no exchange can increase, is released for purposes of his own choosing.
Two and a half centuries after The Wealth of Nations, the mercantilist conviction endures under new names: a nation grows stronger by making more for itself and depending less upon others. Its error is to mistake the appearance of self-sufficiency for the substance of independence, while overlooking how much of the latter has been made possible by the abandonment of the former.
The man on the prairie, if he endured his five years and fulfilled the conditions of his claim, earned title to his land, and he deserves the admiration we give him. His sod house has long since returned to the grass. One of his descendants, we may suppose, still lives somewhere in Oklahoma and carries in his pocket a phone that no person on earth knows how to make from start to finish. He has surrendered nearly all of his ancestor’s self-sufficiency and acquired possibilities of independence that the homesteader could hardly have imagined. The mercantilist in all of us looks at the two men and mistakes which one is free.
