Unfortunately, you are the one who is "seriously confused".
Please, go enlighten yourself. There is no difference between State Socialism and State Capitalism.
And from that:
Most current Communist groups descended from the Maoist ideological tradition still adopt the description of both China and the Soviet Union as being "state-capitalist" from a certain point in their history onwardsmost commonly, the Soviet Union from 1956 to its collapse in 1991, and China from 1976 to the present.
So perhaps rather than 1980 I should have written 1976 - are we quibbling over 4 years now or are you just wanting to argue about terminology rather than actual practice?
(you seem to me to be the type who "just wants to win an argument" so I'm pretty sure I'm wasting my time responding)
You are free to have your own opinion on the true objectives of Mao's revolution. It is my opinion and that of Vladimir Lenin that the "socialist revolution" in the communist sense is to establish "nothing but state capitalist monopoly made to benefit the whole people."
