Maybe we should stop paying taxes since the FED can just print new money when we need it.
The sarcasm was warranted.
I do agree that only the US (or whichever country controls the reserve currency) could really get away with this. But it already gets away with quite a lot, including "exporting inflation," so why not squeeze the dollar for all its worth as long as it's printed by the world's only superpower?
Seems disingenuous.
The actually modern theory has a much more complex lifecycle for money. Yep, government spending creates it, and taxing destroys it, but between all the kinds of money and the entities that can create them, it's not automatic that the government numbers are the important ones.
