This is nonsense. Not a single definition of propaganda, Marxist, liberal, or otherwise, states that propaganda must be state-owned. All media trying to push a narrative is propaganda in some form. Private owners pushing pro-capitalist propaganda is still propaganda.

The systematic propagation of a doctrine or cause or of information reflecting the views and interests of those advocating such a doctrine or cause.

Further, the US does use state influence. Whether it be in the education system, or via state-funded NGOs like Radio Free Asia, the Victims of Communism foundation, etc the state supports the ruling class via propaganda.

but it's (for the most part) not propaganda, because it's not state run.

On the level plain, simple mounds look like hills; and the imbecile flatness of the present bourgeoisie is to be measured by the altitude of its great intellects.

By that standard PragerU is not propaganda because it originates from private funding. Do you wanna go back and think about that one, maybe try again?

How propaganda works in Western capitalist states has been well-understood for decades.
