Control for Oil and Rents and that goes away. Even looking at pre-covid trends...there is absolutely no way 53% of the 2023 CPI is due to after-tax profits. It's
really bad analysis and using after-tax profits and aggregate labor cost index to derive the inference of explained variance when the underlying variable is a byproduct of dependent environment is...uh, well...you're not going to get an answer. Formal tests absolutely wreck their analysis. Just a intuitive check - simply applying pre-Covid weights/controlling for Oil/Rents/Population - after-tax variance isn't even a significant driver of the variance in inflation...it's all Oil(and a bit of Rents) variance, friendo.
