Not all communisms are alike. I was born in ex Yugoslavia (in the early 80's) and I remember its last years when I was a child. By then Yugoslav regime was already deteriorated which led to Balkan wars in the early 90's. However; inequality was for todays standards practically non-existent. Working class people had summer vacations, skiing in the winter, nice big houses, jobs and all the necessities of decent western life. We could even travel wherever we pleased. It was a very soft implementation of communism (there were some gulags for non-obedient but nothing nearly close to what Stalin put in place). You only had to keep mouth shut, but that's basically it. Boomers and gen-Z are (in most part) still very nostalgic of those times here. You still see Yugoslav flags on anti-right demonstrations, Tito's portraits in living rooms, etc.

Of course the price for this paradise was insurmountable; the country was in enourmous debt, productivity was low, and perhaps most woringly; people didn't appreciate what they had. It broke down and a lot of people died. But it was wonderful while it lasted. All those metrics you mentioned were low. Very low!
