This guy almost wrote a book about the multiple theories about multiple theories as to the meaning of money and how it can be accurately measured and which form works best, example Communism vs. Capitalism.
He focused on a supply side theory with data and spread sheets, and only at the end did he hit the nail on the head in my opinion.
The Human cause of inflation, just simple greed.
Check out the profit margins just for oil, and while you're at it, do all the major manufacturers and Wall St.
They all had the most profitable years in years since COVID hit, and your know what?
Next year will be even better because the prices are never going down to pre- pandemic prices.
That wouldn't be Capitalism, right?
