I think this is pretty much accurate. Inflation is basically 100% corporate price gouging, if it was a natural phenomenon the prices of everything would rise at the same time instead of the huge disparities we're seeing between different sectors of the economy. Marxian economist Richard Wolff does a great job of explaining it. I think a lot of leftists are alienated by academic economics, because they only teach free market rules as if they are laws of nature, and therefore might feel less confident debating whether inflation is some magical act of god versus of a conscious policy.
