I'll spell it out more clearly for you, since you didn't seem to understand the implicit point: I sure hope a fellow like him understands supply and demand. I assume he does. But I think that understanding takes second seat to trying to convince people that greedy companies, not incompetent governments, are to blame for inflation. And he writes that (putting aside whether he also thinks it's true) in order to advanced a political agenda. That's why it's in a US politics op-ed section of a left-wing newspaper.
