Bruh. That statement by Marx is an ideal, a metaphor for revolution. No country’s populace has ever controlled the means of production. In fact if you want to take that literally, capitalist societies have for more control over industry than socialist ones do. Modern communism is generally seen as where the government controls the distribution of property. In this sense not even Russia is communist anymore.

And I wouldn’t conflate them because most socialists would be pretty offended to be identified as communist. The average socialist likes Denmark and Sweden. Not Cuba or something.
