Sigh.

A much simpler, more direct explanation exists and is actually supported by data:

"Since the trough of the COVID-19 recession in the second quarter of 2020, overall prices in the NFC sector have risen at an annualized rate of 6.1%—a pronounced acceleration over the 1.8% price growth that characterized the pre-pandemic business cycle of 2007–2019. Strikingly, over half of this increase (53.9%) can be attributed to fatter profit margins, with labor costs contributing less than 8% of this increase. This is not normal."

Most of it has been corporate greed. Period.
