Sure, there has been some, but not nearly as much as people are claiming. It’s evident in the record breaking profits of all the monopolies with food, gas etc. without (and this is key) an increase of margins.
If it was inflation alone, there wouldn’t be a rise in profit due to increased margins. Profits are gapping margins! This is further exacerbated by the lack of a free market existing and driving down prices with competition due to the monopolies.
