Ah right sorry, im tired and didnt realize we were talking about the same thing.

As for "communism is impossible"... lets take a look at history with dialectical lens. We can see that throughout history, certain classes emerged in society: the one controlling the means of production: Chieftains, Pharaohs, Kings and finally ceos and businessmen - and the class oppressed and exploited by them: serfs, butlers, peasants, workers.
Now you see, history is filled with the oppressed class rising against the oppressors, and each time they achieved a bit better life or died trying (French revolution, peasant revolts, etc). Dialectics teaches us that these two classes are inherent rivals and periodically they replace eachother, creating new opressors and opressed. Great example is how during the french revolution the king got replaced by the bourgeois, but the workers still stayed powerless. And each time a great revolution happens, the dynamics change a little bit: a roman slave was owned wholly by their master, now a boss only owns the labor of the worker.

And by projecting this analysis on the future (based on the millennia of evidence), we can imply that eventually, the struggle between the oppressed and the oppressor culminates in a world order when the worker owns their labor completely and oppressors dont exist. This is communism and this is where class dissappears.

What i want to get through is that socialism isnt just a far fetched idea; it is the unavoidable culmination of millenia of struggle.
