When Lenin says capitalism, he doesn't necessarily mean dictatorship of the bourgeoisie. That's what people get hung up about because nowadays the word is inseparable from liberalism. But when he says state capitalism, he's just talking about using the state to direct a capitalist economy. You can do that communistly like how China directs its economy towards renewables, research, infrastructure, poverty alleviation, etc. Or you can do that liberally like how the US gears its economy towards war, racketeering, and debt.
