That happened... but not throughout the entire history of the Union. The Thaw changed a lot, and in the 70s and 80s, everyone simply didn't care anymore. Of course, discussing problematic issues related to the government was not encouraged... but it still might be punished now.
And my opinion is this. I am proud that I was born in this country. That I managed to experience this era, even if only a little. Even if it wasn't the best time... And I am really very sad and hurt that such a great country fell apart. There was no other country like it, and probably there won't be... It's pointless to argue that there were only pros or only cons. There was everything, but for some reason, even with all its flaws, the USSR cannot be compared with modern Russia (even with all its advantages). It just doesn't work... And, to be honest, I am glad that I have the opportunity to study the history of this great country, to touch its part, even if only a little. The idea was grand, it's a pity that it didn't work out to implement it correctly...

Orees, after your post, I felt a wave of nostalgia, I didn't even notice the absence of point 6.
And remember which countries were the first to start working on the atomic bomb (and, as a result, peaceful atom appeared) - Nazi Germany, the USA, and a little later, the USSR. As you can see, two of them had a rigid totalitarian regime, and one had a rigid democracy. There are no monarchical or republican countries here. And what about the space flight? The same countries (except for Germany, of course).
My parents' favorite toast is: "Let's drink to our happy childhood." And childhood was indeed happy. The state took care of its future - of children. Only the highest quality products were available in kindergartens and schools. And what was wrong with the children's pioneer organization?
And now? Expired products in educational institutions, the state simply doesn't care about children. And what have they done with pensioners now? In essence, they said: isn't it time for you to lie behind a low fence, since you can no longer work.
How long did the USSR exist? Exactly as long as people have been asking themselves this question. Everyone has their own view of this country.
