I wish people would stop adding words to my statements, and then arguing based on the added word.
In this case, "directly".
> In fact, before 2020, there is no modern economy where you could clearly point to and say "the government overspent, and caused massive inflation".
Did you forget the 1970's United States?
Expanding on that, from 1800 to 1914 the US had zero net inflation. Zero. We've had inflation ever since. What changed in 1914? The switch to a fiat money system, which enables endless deficit spending.
The same thing happened with every other country that switched to fiat money. Yes, I know about Japan, but not much about it. I did read that they have no GDP growth. The lack of inflation could be because people simply stash their money in the bank, keeping the excess money out of the economy.
