> 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.

It can be argued those systems 'delivered' in spite of their cruel, indifferent, and centralized nature. Not solely because of them.
