Holidays for "enemies of the people" were unpaid
Not true. The GULAG system, which is simply the prison system of the Soviet Union at the time, did pay inmates a wage while they worked there, this is common knowledge and you can check it up if you want to.
and in a quite cold climate of Siberia
Really? The Gulags were all in Siberia? How about you actually check what you're talking about instead of spreading misinformation? From the Gulag museum:

Wow, a ton of Gulags were actually to the west of the Urals, not in Siberia, who would have thought. If only this information was widely available and public...
They also cared about fitness of citizens by ensuring no one has too much of food
Huh? Life expectancy in the Soviet Union rose exponentially, it was below 30 years of age before the Russian Revolution and 60 by the time Stalin died. The diet of the Soviet citizen was by the 60s healthier than that of a US citizen. The CIA itself says this BTW, check out on google "CIA USSR nutrition", you'll find a 1983 document claiming, and I quote, "American and Soviet citizens eat about the same amount of rood each day but the Soviet diet may be more nutritious". Almost as if centering food production around the needs of the population instead of around the profit of food producers, gives a better result...
Just admit it: you don't have any fucking idea what you're talking about. You're repeating talking points you've heard on Reddit or TV without actually checking anything.
