I was pretty happy with my life in USSR, so I definitely would move back if that was to happen. However, I don't really see a path towards that in the foreseeable future. Russia is very much capitalist nowadays, and I don't think there's any real political will to go back to a communist system at the moment. That said, there is no stigma against communism within Russian public. Lots of people who grew up in USSR are still alive today, and they overwhelmingly prefer the old system. They obviously have influence on the younger generation as well, so communism is generally seen in a positive light in Russia. Perhaps now that Russia is falling into Chinese sphere of influence that may result in a similar model at some point.

I think it's also worth acknowledging that USSR did collapse, so clearly it wouldn't make sense to try and recreate the same system. What needs to happen is that people need to look critically at what USSR did well, and what the problems were to build a better system informed by that experience. I hope that happens within my lifetime, but you can never know what the future will hold.
