One problem is that most countries have a silly setup where govt cannot print its own money, it has to lend it from a third party (in the US it is the FED), which means it has to pay
interest on these loans, which makes this approach expensive. Granted, the govt should have been able to print its own money, but it does not seem trivial to change this.
I mean, in practice, most countries end up with such a lending system, which means there is a battle to be fought to get out of it. This will not happen if the masses remain ignorant.
Masses always support government all the way through economic self-cannibalization. The road Covid has paved, governments shall parade over the edge of the cliff at the end.
