Yes, I'd say so. With the exception of drug availability issues, which started if I am not mistaken in the mid to late 70s (basically when the USSR started to really fall behind the West technologically), those aspects worked reasonably well in the USSR.
And before someone says Venezuela or North Korea, the former is a deeply corrupt cleptocracy while the latter used to be the last stone-age version of Stalinism before the whole nation was turned into an open air concentration camp by its dictator.
You've said "reasonably well" a couple times here.... I think there can be book written between the gap of "reasonably well" and "prosperous". And these things are all relative of course... if "reasonably well" is the best in the world at the time, then great. But when you have another system to compare to at the same time, "reasonably well" falls apart very quickly.
I'm not sure if you lived in a Soviet country during these times, but I think you will get MANY opinions that this was not working well.
It is not to glorify the Soviet system. Looking back so, from the end of the Stalin era to, say, the mid-70s, the USSR did compete rather well so:
- military and space tech was mostly on par (a bunch conflicts, incl. Vietnam, show that)
- economically, the USSR was stable
- people were not starving
Of course, the was less luxury and consumerism, but that was true for a lot of other countries as well in Western Europe. It started to fall behind latest by the early 80s on all metrics.
And for Soviet leadership, personal luxuries for the people were simply no priority. And there is no question which system "won" this conflict, is there?
Stalinism lasted until at least his death in 1953. So the period you are describing is all of 20 years, which is essentially a blip on the scale of nations. That same period was also marked by a widespread economic golden age by most of the victors of WWII (France, UK, Japan) and several of the losers (Japan, West Germany), which also ended around the mid-70s, just not as harshly. That’s also around the time communist China started abandoning communist economies for state capitalist ones and started its ascendancy.
So the question is, was communism actually working well in that period, or was it more or less an unsustainable fluke due to the post-war boom era, and as soon as that ended it got left in the dust?
Western Europe, and especially Western Germany, benefited immensely from the Marshall plan. And economic freedom, the early days of what would become the EU and so on. And still, the USSR competed, successfully in the for them relevant fields of sciences and military. And their country didn't collapse doing so. Neither did it collapse immediately after loosing its competitiveness, that took until 1989.
Worth pointing out, Germany outpaced the European allied nations economically pretty quickly, as did Japan.
Being competitive for decades, and the most part of the Cold War, surely is no fluke. In the end, capitalism won out, no doubt about it. Also worth pointing out, capitalism does not lead to freedom, China is a very good example of that.
By the way China, they became the economic power house in the early 2000s. Is the Chinese system a fluke?
