The regime we have is made up of real capitalists, who behave as capitalists often have throughout history. The kind of capitalism that's fake is the Chicago-school free maket kind, which has never existed in real life, because it embodies a contradiction in terms. The market is either "free" as in freedom from regulation, or it's "free" in terms of no oligopolistic barriers to entry. It can't be both simultaneously. Tuly free markets have a lifetime comparable to free hydrogen atoms: they quickly settle to an equilibrium state that's less free (by either definition).
They also ignore literally all of human history when they say shit like that. Hell even the civil rights movement only worked because of Malcolm X's threat of violence.
Malcolm X was a fringe figure: the NOI got lots of press but didn't really do all that much besides indulging in infighting and encouraging local Black businesses. Their approach to politics was separatism. H. Rap Brown, Stokely Carmichael, the Panthers, and many others were more closely involved in direct action.
