Of course they do. The USSR was, objectively speaking, better for a huge chunk of the population. And to top it off, those old enough to remember have rose tinted glasses (it's just natural to remember the good and forget the bad), and those too young to remember have been raised on fairy tales about the before time, and the great long ago, when trees were tall and the country was great. Modern day Soviet nostalgia is in many ways a product of the mythology surrounding the USSR.And yet many rank and file Russians, especially the older ones, cling to ideas of Soviet-style entitlement.
There's also the fact that the climate and geography inevitably leave their mark on the population. Russia is never going to be a country of lots of small private houses, like an American suburb. The heating bill would be insane. Even with the giant multi-storied buildings and central heating, Russia still subsidizes heating and electricity, because if they didn't then the population would be literally unable to avoid the basic means of sustenance. This is, to a lesser degree, true of Ukraine also. It's why the IMF demanded that they raise their electric and gas bills for the citizens, and why ordinary Ukrainians are so pissed right now. But that's a separate discussion. The point is that when ordinary people privatized those giant Soviet apartments, they're left with buildings that have an expiration date, and have no financial means to replace them. Which is why, for example, the Russian government often absorbs the cost of housing. Remember, this is the same government whose officials are notoriously corrupt. This has less to do with a desire to bring the USSR back and more to do with basic reality.
That having been said, the current generation is already very different from the Soviet one, and the clock can't be turned back. The future might carry some of the symbols and use some of the same words as the USSR did, but bringing back the USSR is basically impossible. The Soviet people only became the Soviet people after a bloody civil war, a decade of purges, and finally the crucible of the Great Patriotic War.
