But my main contention is that we had a ton of loose monetary policy for nearly 2 decades with no major inflationary issues.
Then we had a short supply chain shock and a minor catch up in real income and boom inflation. That’s fairly compelling to me.
It’s definitely not mainstream though, I agree with you there, but I would argue that that’s because there’s a lot of people who would have to admit they were wrong for decades if MMT was accepted.
