Who is the greatest economist ever?

Determining the greatest economist ever is subjective and often debated. Many consider Adam Smith, known as the father of modern economics, for his seminal work "The Wealth of Nations," which laid the foundation for free market theory. Others argue for John Maynard Keynes, whose ideas revolutionized macroeconomics and government intervention during economic downturns. Ultimately, the "greatest" economist may vary based on individual perspectives and the specific economic issues being addressed.
