On March 9, 1776, the same year as the American Declaration of Independence, a Scottish philosopher named Adam Smith published a book that would redefine economics. In 'The Wealth of Nations', he challenged the idea that wealth was a hoard of gold. To explain his new theory, he described a simple pin factory. An unskilled worker, he estimated, might struggle to make a single pin in a day, and could produce twenty at most. But if the work was divided, the factory's ten specialized workers could produce 48,000 pins daily. By breaking the process into eighteen distinct steps—drawing the wire, straightening it, whitening the pins—each worker mastered their task. This division of labor created a massive increase in productivity, and for Smith, this was the true source of a nation's wealth.

Frequently Asked Questions
Did Adam Smith believe greed is good?
No. Smith argued that appealing to people's 'self-love,' or self-interest, was a powerful mechanism for cooperation in a complex economy. He carefully distinguished this from raw greed and saw it as a system for strangers to provide mutual service to one another.
What did Adam Smith mean by the 'invisible hand'?
Smith used the phrase only once in 'The Wealth of Nations.' It described a specific case where a merchant, choosing to invest in his home country for security, unintentionally benefits the national economy. It was not intended as a general law that governs all markets.
Was Adam Smith against all government intervention in the economy?
No. Smith identified three essential duties for a government: providing national defense, administering a system of justice, and creating and maintaining vital public works. He specifically advocated for things like roads, bridges, and state-subsidized education.
