A - Communism in theory is a good idea. You do realize what communism entails, right? It requires
i. No private ownership of anything.
ii. A central government that performs all the economic transactions, etc.
The second point is wrong. In the final stage of true Communism, there would be no government, the central government concept is merely a stage, a transitional phase, the
proletarian dictatorship which is a step towards achieving communism.
These are what Marx considered as the progress of Europe's political scenes.
Marx considered that these socio-economic conflicts have historically manifested themselves as distinct stages (one transitional) of development in Western Europe.
Primitive Communism: as in co-operative tribal societies.
Slave Society: a development of tribal progression to city-state; Aristocracy is born.
Feudalism: aristocrats are the ruling class; merchants evolve into capitalists.
Capitalism: capitalists are the ruling class, who create and employ the proletariat.
Socialism: workers gain class consciousness, and via proletarian revolution depose the capitalist dictatorship of the bourgeoisie, replacing it in turn with dictatorship of the proletariat through which the socialization of the means of production can be realized.
Communism: a classless and stateless society.
AND in theory) it is nothing but totalitarianism and inefficiency.
In a nutshell, Communism is a sociopolitical movement that aims for a
classless and stateless society structured upon common ownership of the means of production, free access to articles of consumption, the end of wage labour and private property in the means of production and real estate.
In the schema of historical materialism and in
Marx's theories, communism is the idea of a free society with no division or alienation, where mankind is free from oppression and scarcity. A communist society would have no governments, countries, or class divisions.
In
modern usage, communism is often used to refer to the policies of these governments, which were one party systems operating under centrally planned economies and a state ownership of the means of production. Most of these governments based their ideology on Marxism-Leninism. These governments did not call the system they had set up "communism", instead claiming that they had set up a
transitional socialist system. Mao for one explicitly states the
Revolution was
not over after the Civil War of 1949. This system is sometimes referred to as state socialism. Many, including those on the left, argue that these states never made an attempt to transition to a communist society, while others even argue that they never achieved socialism.
In practice it was. In theory no. Please understand what Communism was on paper and what it was before justifying your points.
