Holding cash is a losing strategy because governments consistently respond to economic crises by printing money. This devalues savings, effectively forcing individuals to invest in assets like stocks simply to protect their purchasing power against inflation.

The South Sea Bubble wasn't just a market mania; it was enabled by government corruption. Directors secretly gave shares to government officials who, in turn, had a direct financial incentive to keep the share price rising, regardless of the cost to the nation. This highlights how state actors can be complicit in creating systemic risk.

Phenomena like bank runs or speculative bubbles are often rational responses to perceived common knowledge. People act not on an asset's fundamental value, but on their prediction of how others will act, who are in turn predicting others' actions. This creates self-fulfilling prophecies.

During the bubble, a lack of profits was paradoxically an advantage for tech stocks. It removed traditional valuation metrics like P/E ratios that would have anchored prices to reality. This "valuation vacuum" allowed investors' imaginations and narratives to drive stock prices to speculative heights.

Bubbles are created when assets like startup equity are valued astronomically, creating immense perceived wealth. However, this "wealth" is not money until it's sold. A crash occurs when events force mass liquidation, revealing a scarcity of actual money to buy the assets.

During the 1980s bubble, Japanese firms engaged in "Zytec," using profits from financial speculation to boost reported earnings. This created a circular feedback loop: rising share prices increased their ability to raise cheap capital for more speculation, which in turn fueled share prices even higher, detaching them from operational reality.

When the prevailing narrative, supported by Fed actions, is that the economy will 'run hot,' it becomes a self-fulfilling prophecy. Consumers and institutions alter their behavior by borrowing more and buying hard assets, which in turn fuels actual inflation.

Governments with massive debt cannot afford to keep interest rates high, as refinancing becomes prohibitively expensive. This forces central banks to lower rates and print money, even when it fuels asset bubbles. The only exits are an unprecedented productivity boom (like from AI) or a devastating economic collapse.

Central banks evolved from gold warehouses that discovered they could issue more paper receipts (IOUs) than the gold they held, creating a fraudulent but profitable "fractional reserve." This practice was eventually co-opted by governments to fund their activities, not for economic stability.
