I am taking one of the foundational documents of the marxist movement as a basis... I feel it might be somewhat more authoritative to start a discussion on the ideas espoused by them. However at this point I give up, it feels relatively pointless to try and discuss Marxism in this thread, especially when to do it properly you need to get into the details of the economic theory versus it's implementations on particular pre-existing socio economics systems.

Just because I can't resist if you are curious, try to read about how Marxists proposed to implement communism, and what sort of pre-requisites they envisioned in order for a transition to be successful, versus how it was implemented in existing societies.
