52/ Ok, I think I get it. MMT says that a deficit isn’t a sign of government overspending, inflation is. (And here they are clearly talking about the overheated economy inflation) So as long as the spending doesn’t cause inflation, it doesn’t matter if you run with a deficit even over a longer period (she mentioned decades).
So basically she is sort of saying that deficits aren’t real because taxes aren’t real.
This is more like the water in a radiator system (my analogy). You can add in water or remove water, but the system isn’t the water. And adding water (money) only becomes a problem when the pressure in the system gets too high and water starts spilling out somewhere.
Basically, money isn’t “real”. It’s… just water in a radiator system in a building. The building and the radiators and the people living there are the real things.
