One of the things communism did right was housing - in the Eastern Bloc home ownership was above 90%. The quality was not great, not terrible. But bad shelter is infinitely better than no shelter. I also think that it also excelled in K12 education. Whether because the german style system that was common in europe pre WWII was just left alone - I don't know. But until the mid 90s we really didn't had the school reformers to fuck it up. Right now we are as good as producing illiteracy as the rest of the west.
