Despite its many critics, it remains difficult to refute the empirical evidence that the capitalist system, with the refinements of Liquidity Theory, has provided us with a set of tools for effectively producing enough. Upset the equilibrium, and the system stops working.
Scarcity can disrupt the equilibrium, causing the system to break down, but so can surplus.
So, the way to keep the system working, according to constant acceleration theory, is to create more purchasing power. That's the nice thing about the monetary system. It isn't real. Whenever we need more money, we can just make more. Ah, but we've tried that.
