My family is in the Czech Republic. My experience has been that the people who are most nostalgic for the "good old days" of socialism are the older folks. Those who were old enough to remember the freedom before 1948 were generally happy to have it return. People under the age of ~35 were also usually happy about it, because they were young enough to rebuild their lives, start businesses, travel, etc. The people I found to be most resistant to the changes freedom brought were ~50-65 years old. They saw rising prices, rising rents, and loss stability at an age when they had trouble starting over.
In the Ukraine, the older folks don't have a democratic tradition from before WWII to return to, so I'd expect nostalgia to be commonplace among retirees. There is comfort in predictability, even if pickings are slim and freedoms are few.
