Two hundred and fifty years after The Wealth of Nations first appeared, Adam Smith has become a totem more invoked than understood. In Washington, his name is deployed as a kind of ideological shorthand, a patron saint of deregulation, tax cuts, and muscular nationalism. Yet the economic landscape of the United States in 2026 bears little resemblance to the world Smith imagined when he sketched the foundations of market society. If he were to survey today’s policy debates, he would likely struggle to recognise his own intellectual legacy.
The anniversary arrives at a moment of profound contradiction. The US, architect of the post-war liberal order and long the champion of open markets, now toys openly with protectionism, tolerates unprecedented corporate concentration, and conducts fiscal policy as a theatre of partisan brinkmanship. These are not the hallmarks of the competitive, rules-based economy Smith believed essential to prosperity.
Smith’s central insight was elegant in its simplicity: markets flourish when competition is real, rules are predictable, and governments resist the temptation to privilege narrow interests. Modern American policy violates all three conditions. Tariffs, once dismissed as relics of mercantilism, have returned as instruments of industrial strategy and geopolitical rivalry. Their political appeal is obvious; their economic logic remains unchanged. As Smith warned, tariffs function as taxes on consumers, cloaked in patriotic rhetoric.
Protectionism rarely declares itself honestly. It is repackaged as resilience, security, or national renewal. But the consequences are familiar: higher prices, distorted investment, and retaliatory measures abroad. The benefits accrue to a handful of favoured industries; the costs are dispersed across millions of households. For policymakers seeking visible action rather than durable reform, tariffs offer the illusion of strength without the substance of strategy.
Equally discordant with Smith’s thinking is the extraordinary concentration of corporate power tolerated in the contemporary American economy. Smith was no naïve celebrant of business virtue. He understood that, left unchecked, firms tend to conspire, implicitly or otherwise, against the public interest. His famous observation that people of the same trade seldom meet without plotting to raise prices remains one of the most prescient lines in economic literature.
In the twenty-first century, the conspiracies are subtler. They take the form of regulatory capture, lobbying ecosystems, and digital platforms whose dominance spans entire sectors. The result is the same: diminished competition, reduced dynamism, and widening inequality. The scale of concentration in technology, finance, and pharmaceuticals would have confirmed Smith’s suspicion that markets dominated by a few powerful actors cease to function as markets at all.
Yet perhaps the greatest distortion of Smith’s legacy lies in the modern caricature of him as an apostle of unfettered capitalism. Before he wrote The Wealth of Nations, Smith authored The Theory of Moral Sentiments, a work grounded in sympathy, social cohesion, and the ethical limits of self-interest. For him, markets were tools, not deities. They required institutions, public investment, and a fair distribution of burdens to function sustainably.
Contemporary American fiscal debates bear little resemblance to this vision. Tax policy has become an ideological battleground rather than a pragmatic exercise in financing public goods. Deficits expand, infrastructure decays, and political leaders compete to promise tax relief without articulating how the state should fund the very systems on which markets depend. Smith, who valued clarity and prudence in taxation, would have regarded this as a political spectacle masquerading as economic policy.
The enduring lesson of Smith’s work is not that markets should be worshipped, but that they must be protected from monopolies, from political capture, and from the distortions of short-termism. Competition must be preserved, trade allowed to flow, and government intervention deployed transparently and sparingly, in pursuit of long-term prosperity rather than electoral applause.
Two and a half centuries on, The Wealth of Nations reads less as a blueprint than as a warning. Markets generate extraordinary wealth only when the rules prevent the powerful from bending them to their advantage. When those rules erode, the system ceases to serve the public.
The paradox of the present moment is that Adam Smith is cited more frequently than ever, even as the forces he feared, protectionism, monopoly power, and political manipulation of economic policy, are resurgent. Were he to observe the world’s leading economy today, he would not be offering applause. He would be issuing a reminder: prosperity depends not on slogans about free markets, but on the discipline required to make them work.
