>a country's GDP simply does not reduce 1000 times in a month, month after month for years. You can not have it if your government isn't printing money like mad.
Yes, but the trigger almost never a government that goes insane and decides to print money like mad. The money printing is ramped up in an attempt to maintain the same level of spending in response to a supply shock.
>Also, no the 4 QEs of the US since 2008 weren't not nearly enough to create hyperinflation.
QE actually causes retail deflation. Which is counter-intuitive, I know.
(the reason is that money printing doesn't cause inflation - spending does, and QE actually reduces spending in non-investment products)
