You forgot to mention energy costs increased 20 to 50 % . Once energy went up with the attack on fossil fuels in this country all costs increased across the board.In the decade before covid, Uncle Sam ran very large deficits and carried a ton of accumulated debt. Inflation was very tame for the period.
Friedman, like nearly every economist, was right sometimes and wrong at other times.
imo, the recent inflationary period was a mixture of broken supply chains, government stimulus money, and pent up demand coming out of covid. How you want to split up the blame, that's subject to each person's perspective, likely.
