Maybe they should try something totally different, a true democracy? I can see how they would be disillusioned now as things haven't gone as promised. Things were not better in the USSR though, from what I've read.
What do you mean by true democracy? You mean US / UK style democracy? Yes... Russia tried it... from 1992 to 2000 (Yeltsin era). And it was a complete disaster. Real wages dropping to one-tenth, inflation in three-digits, death rate increasing to three times that of the birth rate, and oligarchs stealing and plundering the national resources....
Started to change when Putin took over power in 2000. Most of the oligarchs were kicked out, salaries and pensions began to increase, public sector saw a marked improvement and people's live got better. In 2013, after so many years there were more births when compared to the deaths.
I would rate the 2000-2014 period much better when compared to the 1992-2000 period. If you want to go back to the US-style democracy of the Yeltsin era, then I don't think many Russians will agree to it.
