To what Extent had the Policy of Collectivisation achieved its aims by 1941?

Collectivisation was Stalin's answer to his belief that Russia's agriculture was in a terrible state. In a speech in 1928 he said, "Agriculture is developing slowly, comrades. This is because we have about 25 million individually owned farms. They are the most primitive and undeveloped form of economy. We must do our utmost to develop large farms and to convert them into grain factories for the country organised on a modem scientific basis." This statement was correct, …

…a self-sufficient country. However this was the only successful aspect of collectivisation, economically, collectivisation had not really achieved all its aims although it had managed to bring Russia forward agriculturally no Five Year Plan had ever achieved its targets and was still under-producing enough food for Russia. Socially had been the least successful aspect of collectivisation although Stalin was closer to achieving his Socialist society there had been great human loss through famine and brutality.
