Pre revolution, those countries were utter basket cases. Post revolution, they brought land reform (broke up massive land holdings and gave them to the landless), ended their high illiteracy, and brought in much better health care and human services. And they do it despite the West sanctioning, sabotaging, and trying to destroy them anyway possible.

Literally any anti communist story coming out of the West has HUGE provable lies and exaggerations, and it always has massive obvious fascists claiming it. Go ahead, name one "oh but the USSR did..." and I'll show you a story of academic fraud and some guy that thought that Hitler wasn't that bad.
