Why the Stock Market Has Become a Casino

Goldman Sachs facilitated trades by taking on unwanted risk, such as shorting mortgage securities, until a counterparty could be found. They acted as principals, managing risk until a balance was achieved.

During a crisis, widespread distrust can freeze credit markets. Even solvent institutions can face collapse if others refuse their credit, leading to a liquidity crisis where obligations can't be met due to a lack of cash flow, akin to a bank run.

Initial responses led to stiffer regulations and capital requirements. However, over time, antipathy towards regulators and economic pressure to encourage risk-taking ('animal spirits') led to a rollback of some powers, potentially making future crises harder to manage.

The connection can be tenuous. The market extrapolates future possibilities and is heavily influenced by sentiment, sometimes diverging from the day-to-day reality of the real economy. Events like political statements can cause significant market swings.

While the macro economy might be growing and creating wealth, the distribution of that wealth is a significant issue. The gap between those with assets and those without is widening, making the economy not a good experience for over half the population.

The market exhibits characteristics of gambling due to phenomena like meme stocks and extreme price-to-earnings ratios, suggesting irrational behavior and speculation rather than purely rational valuation of underlying assets. This disconnect can have political consequences.
