The time of entertainment per dollar is probably a bit different too I think. Depending on the replayability of the game in question, one can buy a game and get enjoyment out of it for hundreds or in some cases over a thousand hours. Meanwhile, even if you really enjoy a movie and rewatch it like 10 different times, that’s still only like 20 hours. Movies tend to be cheaper to buy than games individually, but I suspect that buying enough movies to make up the time difference would make the movies significantly more expensive.
I assume that the whole “Stalin starved his people” thing isn’t talking about the average conditions of the Soviet Union during more “normal” times, but rather specific events of mass starvation like the Holodomor. That being said, famine caused by accidental or malicious management of agriculture is something hardly unique to any single economic system (I imagine a comparison could be made to the Irish potato famine there, for an example of a similar type of disaster under a different economic system), so I’m not sure if it reflects entirely on the kind of system the Soviets were going for as much as it does mistakes in the process of transitioning to that system, and malfeasance on the part of those in charge in pushing the consequences of those mistakes upon disfavored groups.
