With very few exceptions most of the calamities of starvation or deprivation have been caused by communist policies. That includes the shortage in this country of flu vaccine. Probably 100,000,000 deaths in the twentieth century were caused by deliberately bad policies, the Russian wheat shortage, for example.
Policies are not generally intended to cause calamity. But that is the result. It’s always the result when people who don’t understand economies try to make them work the way they think they should work rather than how they do work.
That was what happened when the farms were turned over to the peasants, instead of the land owners who knew how to farm.
