I have yet to meet anyone who had a strong opinion that anticompetitive practices were not happening. Usually when I talk about inflation, we discuss numerous factors like shortages, the fed interest rate, how some amount of inflation is reasonable to maintain a stable market, etc. And then one of us will say “and there is probably some price fixing going on that we don’t know about”, and everyone will agree that - knowing how profit-seeking companies work - this is probably the case, but we personally have not seen any strong evidence.
