No need for ad hominem attacks. Profiteering has always been a part of inflation but it's never the cause or the underlying reason that inflation occurs. There are a host of things that go into what drives inflation but during Covid it was the Fed dumping tons of money into the system and post Covid it was wage inflation and low unemployment. Do corporations still use predatory pricing? You bet. The only thing that will really work now is either very deep recession or a depression.
