The USSR had to deal with a civil war, rising up during WWI and being sabotaged by the Germans, more civil war, foreign meddling, and all while being the first successful communist revolution. Yet they still managed to raise literacy, raise health outcomes, raise average life expectancy, gender equality, science and technology, end the cycle of famines (after the first one or two they had when they were still building up), had faster growth during that period than any capitalist country (except maybe the US, which was doing imperialism at the time and the biggest hegemon), all while helping sustain other socialist countries, like Cuba, Venezuela, or North Korea.
