You need to look more into the difference between what communist governments said they would do vs what they actually did. No real communist government actually valude manual labor equal to management or intellectual work. This is part of why some modern Marxists insist that true communism has never actually been tried before - because it kind of hasn't. The Russian CCCP, the Communist Party of China under Maoists, post-war Vietnam, Pol-Pot's atrocity of errors - not one of them had independent labor unions, socially adaptive economic corrective mechanisms, or anything near an actual attempt at a equitable society. All of them dramatically valued management over labor - even intellectual labor - they just claimed otherwise.

I don't respect Marxism - I think it was based more around Marx's rage than a real vision, and I also blame it for giving evil men a platform to blame socialism for their own predations. Ultimately, though, Marx himself didn't really seek personal power, and he saw a totalitarian vanguard as a vehicle to establish an equitable society - whereas the systems put in practice drew in men who saw the IDEA of a classless society as a vehicle to personalist totalitarianism. No one ever actually tried to implement Marx's personal vision because the plan itself required at least one generation to be selfless - something that has never happened and never will.
