Once again, you are wrong in how you define communism. Have you even read The Manifesto or Das Kapital ?
If you had you would know that no actually communist society has ever even been attempted in the modern era and that contemporary examples of 'communism' such as China, the C.C.C.P, the D.K.R.P etc are communist in name only.
Communism is the total collapse in the social hierarchy which accompanies an economy in which the means of production are collectively owned by the people of Mother Earth, and their excess production is shared freely amongst them. Communism is practically synonymous with any post-scarcity social arrangement aimed at a humane distribution of the world's resources.
