Oh ya, I should have guessed. There are a couple Baltic states that did increase in living standards and make some rapid industrialization improvements, but they also made some definite mistakes with handling some things there and trying to do some Russia centralization. It made some of those places very right leaning, which is unfortunate.
At least it generally shared technologies improvements and such with those places. It doesn't make the USSR worse than the US, for example, which ruined basically all of South and Central America even worse than the USSR did for its neighbors. I want to emphasize that it made some big mistakes, but for some reason people contribute those mistakes to communism, when the US and other capitalist countries had even worse occupations with even worse exploitation, but for some reason that never leads to people saying capitalism is terrible and awful, etc. The world is just too propagandized by the West. The difference is that imperialism and exploitation is basically required by the capitalist system, while it's a side effect of militarization under a siege mindset for communism. It happened, and will probably continue to happen as long as communism requires capitalism characteristics to jumpstart production, but it's not a constant requirement of the system like capitalism's necessity for the line to go up leading to always finding new markets and resources to take.
