So you admit that inflation is caused by corporations that can raise prices and keep them high? Because, in this thread, you've gone from "this narrative is/was entirely driven by click farming economically distressed people" to "of course they did this, they clearly can" as we've worked our way down to here from my top level comment.
Corporations didn't discover that they can raise prices in 2021. They need headroom in order to do it.
You are confusing the manifestation of inflation (rising prices) with the cause of inflation (more money on the table than hard value underneath it). Yes, rising prices perpetuate inflation (a price-price spiral as mentioned in the research), but the root cause of inflation was not corporations suddenly learning of this new tool called "raising prices". It was a reaction to the unrivaled level of economic stimulus pumped into the economy.
