You should take into account that in 1915 there were dirt streets with pigs diving into puddles and shacks a block away from Kremlin. Only maybe a third of population were somehow literate and life expectancy was around 40 years.
A perception of Imperial Russia is heavily distorted by nobility who emigrated to the West. In their mind they lost a paradise but for the rest it was a bit different. 9 in 10 people didn’t have access to running water or electricity, let alone medicine.
Saint-Peterburg was a single Westernized city in the country, the rest was a kind of modern day India at best.
By the day of Stalin’s death it was radically different in terms of development. They simply went from oxacart to nuclear technology and space program in three decades. It has affected overall quality of life big time as well.
Now your true colors show. Somehow the basest inhumanity and primitive acts of barbarism the modern world had ever known is justified in light of the other “developments” of Russia.
I don’t wish to discuss this further.
