OP is oversimplifying a complex situation. I don't see any contradiction in my remarks.
Government bureaucrats can be part of the working class, but this depends on your definition of bureaucrat. I wouldn't consider an NIH scientist to be a bureaucrat, but some would. Most bureaucrats I would consider to be part of the professional managerial class, which should be analyzed separately from the working class due to their reactionary interests.
I love Xi.
