In particular the corporate profits being cited are coming from ALL non-financial corporations which is a suspiciously broad data set to use when trying to make an argument about price fixing. As an example if there were a shift in profits from small businesses towards larger corporations driven by pandemic behavior, that would contribute to increasing this.
And are we really supposed to believe that near 0 interest rates and unprecedented levels of quantitative easing have no impact on this?
Another thing that’s still worth consideration is that even if 3% of inflation were attributable to corporate profits (it’s probably safe to say he’s exaggerating this a bit at least), is the real rate of inflation actually 6.8%? Many think this is an understated number and the reality may be in the low double digits. If this were the case, corporate profits would represent a relatively smaller portion of real inflation.
