Right, quantitative easing is a similar to MMT; creating money out of thin air. In terms of economics being incorrect from what we had previously known, I meant the theories we follow; roughly 4% unemployment, deficits, & spending. These can all be thrown out the window because the government can create a lot more money without causing inflation, and it should be creating a lot more money right now!
When government injects money in the country, it invests in it. The term deficit is used incorrectly because if a country like the US can create more money and invest it in the country, it owes this money to itself. For example, borrowing money from myself doesn't cause me issues if I am the creator and supplier of money.
DDI is the model/policies we should use to support people/economy, and creating money like we do QE/MMT is how we obtain more of it?
