I run a business. For years I held off on price increases (or kept them to a minimum) because my competitors and vendors weren't raising theirs and the labor market wasn't insanely competitive.
Now, all my vendors are raising prices, all my competitors are raising prices, and all my employees can easily command big raises due to the power they wield in the job market, so I'm raising mine. And all my clients are raising their prices for the exact same reason as me, so I don't have to worry about losing them as clients, I know they can absorb my costs.
This is the viscous-cycle of inflation as it's actually experienced.
Now, that being said, we agree that the "corporate greed" storyline is lame. You see this also in places like Reddit r/antiwork where all companies and bosses are perceived as greedy, malicious labor exploiters. I just feel that behavioral economics is more a cause here than the money-supply forces you're describing.
