By This year marks the 250th anniversary of both the Declaration of Independence and Adam Smith’s The Wealth of Nations — no mere coincidence. The Enlightenment ideals of individual liberty and voluntary exchange that inspired America’s founders also laid the foundation of modern economics. Yet two and a half centuries later, persistent policy blunders — protectionist trade barriers, ballooning national debt, and stubborn inflation — reveal how far we have strayed from the Scotsman’s insights, endangering the principles upon which our republic was founded.
It is tempting to blame these failures solely on politicians. But economists share responsibility. Returning to The Wealth of Nations, one is struck by how little progress has been made in educating the public about sound principles, a task that must be renewed with every generation. While our internal scholarship has grown more sophisticated, the core policy debates have remained largely unchanged since 1776. Smith discredited mercantilism’s fixation on the balance of trade, deeming it “absurd” and a flawed foundation for trade restrictions. He also observed that accumulated public debt is seldom repaid honestly; governments instead print money and erode purchasing power. These debates sound strikingly contemporary.
After 250 years of theoretical and empirical advances, including 99 Nobel laureates, why do governments keep repeating the same mistakes? As Deirdre McCloskey has noted, the field of economics suffers from Smithian specialization without Smithian trade: narrow expertise unaccompanied by broad intellectual exchange. In a 1976 bicentennial assessment, Terence W. Hutchison criticized the profession for narrowing its scope, assuming a stable social and political backdrop so as not to disrupt isolated economic analysis. This approach excels at precision on narrow questions but neglects the wider terrain of political economy, driving a wedge between academic research and policy relevance. Smith’s “system of natural liberty” demanded the comprehensive foundations he provided — not fragmented silos.
This internal refinement has come at the expense of teaching basic principles effectively. Smith contrasted the lively instruction at Glasgow, where professors’ pay depended partly on student fees, with the uninspired, often absent lectures at Oxford, where compensation was fixed regardless of enrollment. Incentives shape behavior, even among economists. Modern academia rewards narrow research over conveying fundamentals in the classroom or engaging the public, leading to a widening gap between specialized technical research and actual debates that shape policy. Novelty, not timeless wisdom, drives top-journal publications. Delivering a mundane walkthrough of textbooks or PowerPoint decks passes for “teaching” in far too many classrooms.
Graduate programs tend to emphasize exceptions to Smith’s core ideas, however tenuous, over the principles themselves. As Bryan Caplan has noted, graduate students start their programs already steeped in market-failure arguments, and two additional years of mathematical theory presenting “dozens of esoteric ways for markets to fail” will only reinforce this worldview. The approach neglects the principle that when individuals are free to pursue their own betterment, beneficial social coordination and order emerge spontaneously. The system of liberty — called common sense at our nation’s founding — reflects how order arises without central design if government is limited to “peace, low taxes, and a tolerable administration of justice.” Market failures are the exception, not the rule.
Focusing economists’ training primarily on market failure is like training physicists only to probe exceptions to natural laws while ignoring the universe’s consistent regularities. It encourages siloed experts to recommend “minor” interventions, as if executed by a host of benevolent bureaucrats, which aggregate into a system of control entrusted to fallible politicians, not angels.
Hutchison closed his 1976 remarks with hope that by 2026 economists might reclaim Smith’s broad foundations. Fifty years on, the drift has only deepened, underscoring the urgent need for introspection. If not economists themselves, who else will uphold and popularize genuine economic principles and make the case for laissez-faire in the spirit of Adam Smith?
In this shared 250th anniversary of 1776, economists should reclaim their Smithian inheritance: teach the timeless truths of a system of natural liberty, echoing the Enlightenment ideals that birthed both our nation and modern economics.
