That's also true of the satellite countries, but they seem to have flourished after the fall of the Soviet Union, pretty much all of them now members of NATO. Russia never quite got over the loss of its Soviet empire, but they went through a very rough patch in the 1990s. I visited in 1997 for a few weeks and saw some scenes of serious poverty, including people begging on the streets. The Humanities building at Moscow University was running a perpetual flea market on the ground level. Putin repaired and stabilized their economy in the early 2000s, and that is primarily what made him popular. They did experience about 15 years of relatively strong democracy, but that all faded as Putin began assuming more and more power.
Among my friends at the time of my visit, one faculty member at Moscow University complained bitterly about the economy, but she said that her greatest fear was that the same people who ran the Soviet Union would come back into power. It took a while, but that's who is in charge now. It was clear to me, judging by all the demonstrations and state actions to suppress the democracy movement, that a great many Russians, especially the young and educated, had a very strong yearning for democracy. The fact is that even Belarus and Ukraine had strong pro-democracy movements. The Ukrainians succeeded in moving in that direction with the Maidan Revolution, but Belarus was not able to overcome Lukashenko. Belarusians and Ukrainians are really not much different from Russians. They just had different circumstances, including a resistance to attempts by their neighbor to reestablish Russian hegemony.
