Ideally it evolves after capitalism has reached its total and most unbearable climax, from the masses themselves. It is not brought about by violent revolution (Latin America, except Chile), the aftermath of war (China), or by a dictator (Cuba, USSR, etc.). In Chile a socialist leader was elected by the masses, but was stiffled by the US and the North. Even a democratically elected socialist does not qualify as the ideal method of transformation. Marx envisioned the gradual erasure of government (i.e. the state) itself, and a drastic shift of power to the people themselves. This is what I'm refering to when I say it has never occured.
