The problem with “mixed economy” framing is that no economy is pure, and every economy has a principle aspect. There’s no such thing as a state with class “harmony,” so one class must be on top. China is socialist because public ownership is principle, Scandinavian countries are capitalist because private ownership is principle.
The only way to end this is for all production and distribution to be collectivized, abolishing class, and therefore class struggle eventually, which requires protracted periods of socialist transition.
