Why? Because the term isn’t neutral.
That's what I said; the center defines the standard. The US is authoritarian by social-democratic standards.
They emerge and transform through shifts in the mode of production and the intensification of class struggle.
"Class struggle" is not a one-dimensional variable, and the mode of production is to a significant extent a choice made by those within the system. A revolution has degrees of freedom for who is in its circle of solidarity.
Anarchist models that treat authority as a contaminant to be minimized misunderstand the state as a neutral tool rather than an instrument of class power.
State communists mistake the state/vanguard as a neutral outsider rather than a material entity. Authority left to fester will shape the material conditions to enshrine the authority at the cost of those without authority.
