yes, to actually believe in communism you must ignore or not understand a few very core, intrinsic traits of human nature. they're already detached from reality so of course managing anything or doing anything useful in the real world is beyond their abilities.

also, as you said, they're lazy and greedy. but also lack any humility, honest self-reflection, or real understanding of their own capabilities. they all think they will be the shot-callers and not the slave splitting rocks in an open pit mine. which is where they belong.
