This post notes that there is one historical example of a successful Marxist economy. It required that everyone give up sex.
Don’t expect to see another successful one in this lifetime.
There’s another thing …Shakers practiced what they preached. Even the “movers” of the Shakers. Elders and leaders lived exactly as others did. Oh, they “had” desks or offices, in the sense they needed them to do their jobs. But these possessions weren’t the elders’, they were the commune’s.
And the leaders ate and slept and lived exactly as the others did. High offices profited them nothing.
They’d make a lousy Politburo. Or any of today’s multi-millionaire “socialists”.
