the working class is in control of socialist authority
Independent unions are illegal in China with only the All-China Federation of Trade Unions (ACFTU) permitted by the Chinese state and the Chinese Communist Party to operate. Seems to me like you got it backwards, the "socialist authority" is in control of the working class. Any who attempt to organize on their own terms are met with state repression. Your insistence that the Chinese state only oppresses capitalists, fascists, and saboteurs is provably false.
