Theory of Laissez-Faire – Developed by Adam Smith:
The Theory of Laissez-Faire is an economic philosophy advocating minimal government intervention in the affairs of business and markets.
This theory was developed by Adam Smith, often regarded as the father of modern economics. In his seminal work, "The Wealth of Nations" (1776), Smith argued that free markets, guided by the "invisible hand," efficiently allocate resources and promote economic prosperity.
According to this theory, individuals pursuing their self-interest in a competitive market environment ultimately benefit society as a whole, without the need for heavy-handed government control.
