I agree, to a certain extent. WHile there were both benefits and harmful side effects, it brought more harm than good. Take for example the 1932-1933 Famine, in which about seven million peasents starved to death due to the food shortages due to collectivization, which was one of the Economic Policies. The economy and people suffered, as the number of livestock also decreased, due to Stalin wanting equality, he tried to get rid of the Rich Peasents , who were labelled Kulaks, and he wanted them to hand over their belongings, like their land, livestock and crops. They instead decided, they would rather kill and eat their animals, rather than give it to him. However, it did help improve the economy somewhat. There was an increase in grain production from 36 to 95 million tons from 1920 to 1940, however, it was not much of an improvement from pre Revolution figures, which were 86 million tons. In essence, while there were benefits, the cons outweigh the pros, and it was more detrimental, than beneficial.
