The economic theory that views economic success in terms of real money is

Monetarism.

Monetarism is an economic theory that argues that money supply is the main driver of economic growth. As the money supply increases, people demand more products, factories increase productivity and new jobs are created. The increasing money supply, however, only provides a temporary boost, as in the long run it is likely to increase inflation.

Monetarists favour monetary policy over fiscal policy (government spending and tax policy).
