He did that with the explicit goal of undermining his socialist opponents (so people wouildn't have a reason to support them)
In regards to your second point, lol no. That would be communism. I'm glad that you think left wing policies are common sense though? Most of us heavily agree which is why seeing the proliferation of conservatism is disheartening.
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.
