• 🔄 The Great Depression highlighted the limitations of classical economics and led to the rise of Keynesian economics, advocating for government intervention in economic downturns.
• 🏛 The Austrian School of economics, with figures like Friedrich Hayek and Ludwig von Mises, opposed heavy state involvement and argued for the complexity of the economy as a reason against manipulation.
