I also love how these imbeciles always bring up the fact that USSR dissolved as some kind of gotcha, like see communism doesn't work I'm so intelligent. As if no capitalist regime has ever collapsed due to its internal contradictions. The reality is that every type of system has potential to fail in some way. The question that actually needs to be asked is how well the system functions while it's working as intended.
USSR managed to provide everyone with things like food, housing, education, and healthcare. Nobody in USSR worried that they'd lose their job and end up on the street or that they couldn't retire in dignity. These are basic things that no capitalist regime is able to accomplish today. These are real tangible rights and freedoms that USSR ensured for its people.
