Socialism is just a softer step on the slippery slope toward communism.
Communism does not exist. It’s described in the Manifesto as “an association in which the free development of each is the condition for the free development of all”, which is a meaningless description devoid of specifics.
This is supposed to be the point where the all-powerful socialistic state somehow “withers away” after it’s somehow discovered that the socialist state wiped out all of the bourgeoisie and the “society” with no family, religion, private property or borders can exist without the all-powerful state.
