Jfl. Rule by committee or council is still rule by social manipulation. In fact it makes it even easier. Say something goes wrong in a committee setting. Who gets blamed? Think hard. The person who has the least social capital. or "external" factors. Competence is not needed if you know somebody or are part of a clique that will back you no matter what. Cliques and social capital are the tools by which incompetence is preserved in government. If these people also happen to have friends in the media and educational institutions (hint: they do/will), they will control what will be said of them and society's perception of them as a result. See us as an example. A trucel makes a comment about lookism. He is laughed at. Some Chad says the same thing. He is praised. Marx said very little about the nonmaterialist factors that play in human behavior. IIRC he didn't even talk about lookism or genetic factors in human decision making.
And a key component of communism is workers owning the means of production. How has work usually been allocated in these arrangements? By democratic vote and trade unions of course! So you're back to the familiar problem of incompetent leaderships backed by cliques.You aren't liked by the group? Too bad, go clean the toilets while chad and his crew work the easier jobs around the factory. Inceldom is fundamentally a social capital problem. Any system that requires social capital to advance in it will disadvantage people like us.
