On March 11, 1776, The Wealth of Nations was published, a work by Scottish philosopher Adam Smith that forever changed the way we understand the economy. It has been 250 years since Smith described the mechanisms of the market, the specialization of labor, and the enigmatic ‘invisible hand’ — the idea that personal interest, in conditions of free competition, transforms into social benefit.
Smith believed that the primary regulator of economic relations should be the market, or the invisible hand of the market, rather than the state. Although the world has radically changed since the 18th century, Smith remains a fundamental author for understanding everything from global trade to today’s technological economy.
Productivity More Important than Money
The essence of Smith’s thought lies in the simple yet profound realization that true wealth does not lie in money, as mercantilists claimed, but in useful labor, or productivity. Productivity, in turn, grows through the division of labor, innovation, and open markets.
Smith lived at a time when manufactures and global trade were emerging; today we live in an age of artificial intelligence, digital platforms, and technological monopolies. Yet, the same questions remain: what drives growth? How to organize the market? When may — or must — the state intervene?
Comparisons with Keynes
This is where the comparison with another giant of economic thought begins: John Maynard Keynes. If Smith explained how the economy grows when everything works, Keynes explained 160 years later what to do when nothing works. Smith believes that the market returns to equilibrium in the long run; Keynes warns that it can get stuck in crisis for years.
Smith argues that competition and free exchange are the engines of prosperity; Keynes that the state must step in when demand collapses and people stop spending. Smith speaks of the long term; Keynes of saving the present.
Two authors, two centuries, and two different worlds — but together they form the foundation of modern economic policy: from free trade and fiscal stability to counter-cyclical measures we have seen during the pandemic, energy crisis, or inflation wave.
