Not true actually. Many/most countries did massive increases in money supply. [0]
I don’t know exactly how each country compares to the US and was only using the US because of others in thread and that’s what I know best.
In the US it’s assumed to be additional income because you can measure money supply and see the increase. So it’s a correct assumption because there’s just much more cash. If it was replacement, then money supply would stay level.
Also, in the US direct cash payments weren’t need based. Everyone got them despite income or necessity. Personally, I stayed employed, got overtime, and got $8k+ in direct cash deposits. Just an anecdote, but everyone I know got similar payments. So it always seemed odd to me that yuppie programmers got wads of cash. The rationale made sense as they needed to help people quickly and qualifying would slow things down.
But this is a macro example of inflation drivers. So anyone with basic economics training would recognize this example. Arguing otherwise seems silly, without lots of evidence.
Corporate greed is constant and universal.
