They're repeating propaganda about communism and socialism.
It's tiresome, really, the degree to which Americans have bought the propaganda that countries like the Soviet Union themselves spread, that they were communist, when in fact they were authoritarian dictatorships with a few very-badly-thought-out planned-economy features.
Please then, what was it? Capitalist? Feudal? Democratic socialism? I need a clear answer..
It's obvious that "communist" policies don't entail that you have the same government as the USSR, so I think it's fair to call arguments that suggest so propaganda. It's probably meaningless to argue about whether the USSR had "true communism".
That's the problem with this type of topic. As much as I like to talk about it, there never seems to be any real talk. People pick a side and arguments be damned.
The extent of their knowledge generally extends to "communism bad" and there's no good faith in actually talking about the shitty situation we're in today.
My original answer was not even citing communism at all. I was specifically talking about worker conditions, but people seem to be unable or unwilling to have a conversation and instead degrade it and down vote.
