A Marxist-Leninist state should just ban the intentional spreading of that kind of blatantly wrong “economics theory”. Literally, filtering out capitalist nonsense so the people don’t have to deal with capital’s bullshit is one of the purposes of massive federal government censorship of the country’s media access and regime tools like China’s alleged Great Firewall. Anyone talking about economics who isn’t a Marxist should be deplatformed in a socialist state context. No one wants or needs to hear their misinformation.
