Capitalism is the last expression of class rule.
The economic foundation of class rule is the private ownership of the necessaries for production. The overthrow of class rule means the overthrow of the political State, and its substitution with the Industrial Social Order, under which the necessaries for production are collectively owned and operated by and for the people. Goals determine methods. The goal of social evolution being the final overthrow of class rule, its methods must fit the goal. As in nature, where optical illusions abound, and stand in the way of progress until cleared, so in society.
