You wrote: "Everything I have done lately has been sources from reputable text books." A quote taken out of historical context and placed into some illogical place may significantly distort the truth. An example is your sentence "It was not until the 1950s that Soviet farm animals approached their 1928 levels" In your text one may conclude that it was all fault of collectivization. Because your  omitted the catastrophe of 1941-1945, which threw the economy of the country into middle ages. In addition there was a severe drought in 1946, which hit about 50% of the arable land. And in fact it was miracle (actually very hard labor) that industry and agriculture was recovered in mere 5-7 years.
