In this foundational classic, Adam Smith puts forward the theory that a nation derives it’s prosperity from the division of labor, free markets, and the accumulation of capital. His idea of the “invisible hand” explains how individuals, while pursuing their personal interests, end up benefiting society by the efficient use of resources and advocated for open competition and limited government intervention. A nation’s true wealth, he says, lies in its productive capacity, rather than its reserves of gold and silver.
