The pure communism you ask for is a modified anarchist system, left and right meeting and annihilating.
It cannot work. People will always work for their own good.
Precicely. This is the main reason communism fails. The idea of a "collective" society is nice on paper but in truth it is completely unrealistic due to the fact that it breeds laziness and apathy. There is no sense in hard work because no matter how hard one may work there is only so far up the ladder one may go under the communist system - thus - eventual apathy and resentment.
Oppression will undoubtedly come into play as there are those who cannot be stifled by the system and will eventually try to gain more and the need to put them "in their place" will arise. Who will do this but the government? Someone will always be in "control", like it or not. It is a fact. This is not to say that government should be in control of all aspects of life. Obviously this is not the case. A system such as that if the USA is indeed the ideal, although not perfect, but then NOTHING in this world is perfect when one is dealing with fallible human beings.
Anyone who truly believes that a communist system is workable and a good idea most certainly deserves the ZOT.
So, ZOT to you, Sammy Sam! ;)
