The USSR collapsed over 30 years ago. There's a lot of people who were born after that, or who saw their quality of life improve after it happened. I bet you not many of them want to go back to those days.
The death rate in Russia went way up after the fall of the USSR.[1]
Democracy and a free market did not deliver a better life for the average Russian. It's important to understand this, because it's part of why Russia ended up with an autocrat.
Note that the Russian economy was still organised around a Sovjet planned economy. Just because you change the legal system doesn’t mean you have fixed the economy instantly. For example there were still monotowns, where the whole town was centred around a single factory. These towns are extremely fragile in a market economy.
> who saw their quality of life improve after it happened.
The end of the USSR is widely considered a humanitarian catastrophe because after the economy colapsed, people had no food, no medicines, no order, it was a wild west for several years (my wife was there, she tells me all about it)... where the hell did you "learn" that people's lives improved after the USSR fell??
