No kidding they didn't. But show me a worker owned society that didn't end up that way. How safe are people from the government in North Korea? Why is China only becoming a superpower since it turned to capitalism?
As for the US, we're not angels, but, you mean killing people with drones who mostly would be flying airplanes into buildings or driving into crowds with rental vans because (insert deity here)? Those aren't political dissidents. Those are people who think they should be killing "others". Some people won't listen to reason, and need to be decimated by force to be defeated.
And your basic drug dealer lives with his or her mom because he
makes 20-30k a year. He just doesn't want to have to wake up early or be where he's supposed to on time every day because he's a loser, not because he's oppressed. Great thing about dealing is you sling when you feel like it.
Prisons - idk. I don't think people should be locked up for a joint, and Netflix has found a few people who shouldn't be locked up in their documentaries, but when HBO interviewed the "toss my salad" guy, well, I'm glad that guy is (was?) in jail. I don't think he ever becomes a reformed, productive member of society.
