communism does not inherently mean authoritarian dictatorship
How does that work without fair elections?
Marx didn’t invent communism,
Maybe not, but his definition is the basis from which all others are derived. So any other form needs to be specified IMO.
I am very well aware that no 2 practical attempts at implementation are alike. Hell some of them aren’t anything more than simple dictatorships, like North Korea.
Mostly Free Markets regulated to some degree, but even communism although they don’t really have free markets, they still have markets and companies. They are just regulated by quotas instead of supply and demand. And economically that model simply doesn’t work. Just as a 1 party system has always shown to be authoritarian.
