I am no expert but I see a lot of people debating if corporate greed is causing inflation or not. My impression is that inflation at its root is always caused by money printing, however things like price driven greed that capitalize on this fact drive it further in a direction that puts people at a disadvantage. I don't think it is a root cause but if it is currently a driving factor contributing to a problem, it is worth addressing.

I don't know what you do about it though. Price controls would be stupid.
