> If only Marx et al. knew that the end game of capitalism is communism!

Using "end game" as it seems to be here -- for the natural ultimate result -- Marx argued that as a pretty central thesis of his work (through the mechanism of capitalist development -> proletarian class consciousness -> socialist revolution -> socialism -> <stuff mostly left as an exercise for the reader> -> withering of the state -> communism.)

OTOH, a single entity run for the benefit of a narrow group of stakeholders employing all labor, supplying everything, and effectively enslaving everyone through private control of the means of production is not Communism, or even socialism (defined by proletarian control of the means of production) but just monopolistic capitalism (and, yes, this is where a major non-Leninist Communist criticism of Leninism, and its descendants like Stalinism and Maoism, that feature totalitarian control of a command economy by a narrow self-perpetuating party elite stems from.)

People always criticize that, and yet those systems delivered: They raised the Soviet citizens from mud huts to apartments within one generation. One thing that is prominent in the stories about the fall of the Eastern Bloc and its aftermath is how the Soviet citizens never thought that they could lose 'staples' like free education, healthcare, childcare, housing, food, paid vacations, maternity leave, guaranteed jobs etc in capitalism. They thought that they would have everything that Leninist socialism gave them in the USSR and an additional consumer economy. They were dumbfounded to find out that wasnt the case.
