The market is broken because investing in stocks gives the best risk adjusted returns, meaning investors refuse to invest in businesses and would much rather just dump money in equities. Large companies also refuse to devalue their stock (issuing new shares/raising debt backed by equity) since that would piss investors off, so stocks remain high. Look at the cash returned to shareholders of most large tech conglomerates. It's effectively zero (with the exception of Oracle which is running the largest ponzi scheme in world history, ie their debt is literally rising exponentially: https://companiesmarketcap.com/oracle/total-debt/ -- looks like a chart of hyperinflation, and all they're doing with this debt is paying out dividends).

Once the bubble pops you'll see either hyperinflation and renormalization of currency, or severe deflation. Nothing in between.

This hypothesis has been repeatedly tested by various attempted device competitors.
