The General Theory of Employment, Interest, and Money
We often hear that markets are self-correcting, that any economic downturn is just a temporary blip before things naturally rebalance. This comforting idea suggests that if we just wait, the invisible hand will guide us back to full employment and prosperity. But what if that's not always true? What if an economy can get stuck, not because of a lack of resources or desire to work, but because of a collective paralysis, a shared hesitation that becomes a self-fulfilling prophecy? It’s a familiar feeling when a company, despite having cash, delays expansion because of a general unease, or when consumers, feeling insecure, save more and spend less, creating a downward spiral. John Maynard Keynes fundamentally shifted this understanding, revealing how human psychology – our 'animal spirits' – drives investment and consumption, and why deliberate action is sometimes the only way to pull an economy out of a persistent slump. He showed that waiting for things to fix themselves can mean years of unnecessary hardship.
