What is Capitalism?

I'm not sure if this is serious or not.

I could get a capitalist to tell you how great their system is, but instead I'll get someone who's a critic of capitalism to. Marx had some serious flaws and limitations in his socialist ideas about things, and some went on the be completely corrupted (communism), but he was a magnificent critic of capitalism.

Here's Marxist Professor Richard Wolff:

I enjoyed Wolff and his ideas about worker cooperatives until the lockdown which he hasn't been remotely critical of, nor critical of the SJWs, BLM, etc. Most importantly he keeps pushing Marxism/socialism/communism as if it's going to solve anything when clearly big government and the corporatocracy are the root of ALL problems.
