The whole concept of paper money is bullshit. MMT is another layer stacked on top of a foundation of bullshit, so how can you determine if it is bullshit or not?

In our system of paper money and a central bank, there are two people who benefit from inflation.

1. The financial industry benefits from inflation all the time, as the Federal Reserve "monetizes the debt".
2. The government benefits from inflation whenever it has deficit spending.

MMT is the government claiming its "fair share" of the wealth stolen via inflation. MMT says that, as long as there isn't a hyperinflation of the money supply, deficit spending doesn't matter. Government can always issue more debt and refinance its loans.

The national debt does not represent an amount that must someday be repaid. It can be rolled over indefinitely. In fact, trying to actually repay the national debt would need tax hikes or spending cuts that would cripple the economy. The national debt represents a running total of stolen wealth, and not a debt that should be repaid.
