Interesting conclusion, I can somewhat agree that the abstract writings of Marx did not produce in practice a direct reflection of the writings. The original flaw though, which I think we both agree about, is the intervention of the state in either case.
For example if workers want a union, great setup a union, but you don't need permission from the state to bid for wages. In fact you do not want the state to help, because then they get a cut and can take away this "right" whenever they want. The state is not the best instrument to deliver rights, the state is far better at taking away rights, which I think causes the issue of totalitarianism. Great conversation, really appreciate the discuss.
