1. What was Karl Marx's basic premise and belief?

Karl Marx's basic belief was that the working class will start revolution in the most developed capitalistic countries. One of the basic premises of his thinking was maybe expressed in the first sentence of his The Communist Manifesto: "The history of all hitherto existing society is the history of class struggles." He claimed that human societies progress through class struggle: a conflict between an ownership class that controls production and a dispossessed laboring class that provides the labor for production.
