>Corporate profits
In the social media circle-jerk, yeah. In economist circles that include the advisors consulting on policy, no. Corporations are/have always tried to maximise cost and profits. They didn't suddenly decide to get greedy 18 months ago. "Blaming inflation on corporate profits is like blaming gravity for a plane crash, technically right but totally misguided." Remember, gravity is always trying to crash a plane.
Frankly I will always side with expert opinion over karma farming social media commentary. I know it feels good to blame the shadowy cabal of fat men with a top hats and eye pieces, but it's just not what is going on.
