> I’ve heard that, under socialism, workers would vote on who they want to be managers...
I grew up under socialism and wanted to mention that author "heard" very, very wrong. Under socialism, the Party bosses will decide who will be the managers. The person's qualifications and achievements will be largely taken into consideration, together with their loyalty to the Party, who their parents are, friends in high places who vouched for them, favors that need to be returned, etc... Not that much different from the capitalism.
The process author describes, is what happens when you are thinking to become a socialist society. Everything looks fantastic then. But actual socialism comes with removal of democratic safeguards and somewhat totalitarian government (how else would you confiscate private property from citizens?).
Once the new, socialist, management is in place, they quickly realize that it's nice to be at the top. Next, they turn their attention to the authors like this (who threaten their permanent place at the top) and quickly "dispose" of them. There is a sweet irony in this process, but it is of little consolation for the rest of the population, who will suffer for the next 70 yrs until the country goes back to the capitalism.
