The Money Printer is actually good, and The United States Dollar as a Global Reserve is beneficial because The United States Dollar provides global liquidity, without The United States continually printing The Crurrent Global Economy would not exist.

The issuance of new money allows for other countries to rely on The Dollar as a global trade standard, and legitimizes The United States position in the global order.

As more currency is printed the wealth of other countries will increase as more economic activity will be spurred.

Additionally this allows for assets to increase in value, and companies to generate new wealth, and value.

The only downside is that savers, and workers lose out but that's a skill issue if you don't have assets.
