"The Wealth of Nations" by Adam Smith is a groundbreaking economic treatise that explores the principles of capitalism, free markets, and wealth creation. Smith argues that self-interest, guided by an "invisible hand," drives innovation and prosperity, benefiting society as a whole. He critiques mercantilism, advocating for division of labor, competition, and minimal government intervention in trade. Through detailed analysis, Smith examines productivity, wages, profits, and taxation, laying the foundation for modern economics. His insights into human behavior and market dynamics remain influential, shaping theories on commerce, ethics, and societal progress.
