The "economy" isn't dependent on growth per se, our monetary policy is. If we're not constantly consuming and printing more money (fueling the ponzi) then the economy collapses.

This notion of constant "growth" refers to markets always going up over time "growing", but that's just a result of excess money printing. In reality, the economy has been stagnant, running an upstream battle for decades against fiat.

We've plateaud economically speaking until we fix the money. Our advances across all industries wont translate to a better quality of life for the world until monetary policy gets fixed. It'll just keep getting siphoned to the top at the expense of the rest of us until then.
