Of course, the Soviet Union didn't collapse at all because guys listened to jazz. If you connect a good neuron, and even our pure corporate lady, you can convincingly prove at the level of such a strong humanitarian doctor that the phrase that the Soviet Union collapsed because of lies is not a spectacular journalistic phrase, but an academically correct conclusion, simply stated in a primitive everyday way. A lie, and an ideological stagnation (in fact, a very cool descriptive and socio-engineering concept) of Marxism-Leninism, which, due to this stagnation, has ceased to satisfy the needs of at least some thinking people. Lies and stagnation in public consciousness are interrelated. Everything else is either secondary (as the experience of modernization in China proved), or a primitive conspiracy theory (if the system was so strong, how could spies get to the top?) and it is this very stagnation, and the lies expressed in double standards of thought and behavior, that gave birth to such prohibitions.
