Yes, they had. It might sound cinycal to you, but if you could imagine you are not german, but russian, and (who'd guess?) you have your own interests, you'd might understand. They wanted to move the borders from Leningrad, which was 2nd capital of USSR. You can start yelling "You commie bastard" right now.
Stalin did a huge thing to USSR, but at the same time, he was a paranoical maniac. But you, "Western people" (sorry for generalizng) want to hear and speak about the last. You just can't (or simply don't want to) understand, that while he was a leader, country got up from it's knees and survived, no matter what. You think that it'd be better for russians if they'd had next tzar? Remember what happened in WW1 and Russia-Japan war? we f*cked up heavily.
Now about "ahh back in the SU we had schools, work whatever". Yes, people had. Have you ever seen or talked to old people in post-soviet union? I'm really amazed, how can they still live (they get about $100 and the cost for their flat IS about (a little bit less) $100). Pensioners were always important in Soviet Union, as were students, simple workers, military men, doctors, teachers etc. There were much more good sides of SU than bad. Stalin did not had gas chambers, he did not order to kill all invalids, he did not say that only russians were ubermenshen, in fact, people of all 15 republics were even. Even the black people (and you know what was the attitude to them in USA back then), so please don't compare him to hitler, k? Stalin died in 1953, but USSR left to you, western people, the same. You did not lived here, you have far less experience to judge. I was born in USSR, so as all my family, as all my friends. NONE OF THEM think it was a bad time and place for them, not even old people (who were born in 1920s and saw what happened in 1937). I don't want to be back in the USSR, but i don't think it was Empire of Evil. In fact, i think in some (a lot) ways it was better that Western countries.
Besides, if you had some knowledge on economics, you'd know that the whole "prosperity" of the USSR was a fat-ass bubble, nothing more. No matter how grim things look now for some of the former Soviet countries, to think they would be of better with the SU intact is a blatant lie.
Now i don't compare modern post-soviet union with the SU itself. I'm saying that here, in the centre of Europe they teach us that it'd be better, if we'd stick to Third Reich.
