Yeah, but Yugoslavia was unsustainable.

Employment and housing for everyone is great as long as the population is growing and the government can get cheap loans.

High quality public education and healthcare is great too, but that doesn't require a communist regime, because we still have that and no communism.

One dead leader and economic crisis later and the whole country collapsed in a brutal war fueled by nationalism.

My parents speak fondly of growing up in socialist Slovenia and they really didn't want for anything, but I would never prefer growing up there instead of the current democratic Slovenia.

It might be different in poorer ex-Yu countries, though, Slovenia is a bit of an outlier there.
