Did I ever say they were/are saints? The OP was commenting on their poor "country building" which I interpret largely as economy building. It was a horrible place to be
Yes hunger was problem in the civil war to world war 2 era with some really horrible famines but famine was also a regular occurrence in Tsarist Russia to begin with.
Now there is the discussion to be had of whether they were "man-made" or not and that is indeed a important discussion but that also needs to be contextualized: Historically capitalist countries going through industrialization have also seen famines.
In an alternative universe where the October Revolution did not succeed, can we honestly assume that there would have not been any famines? No, so there is not a direct causality. (Again, note that I purposefully not talking about specific events and responsibilities but instead showing that these question are not relevant for the big picture discussion.)
It is a common mistake in the study of history to confuse structure and specific events. Was hunger a structural, common occurrence in socialist countries? Absolutely not.
