You are wrong, I'm afraid.
Collectivisation was great success of Stalin regime. It answered next most important problem of Soviet Union:
1. Russian culture was really detriment in political sphere in comparison with Western culture. It had some reason as well: Russia placed in very unfavorable climatic zone & have really fickling outcrops in any year. If you check Russian annales ("letopisi") you will find that any year she got some zone with poor outcrop & some other zone with good outcropping. When Russia was Monarchy this problem had next solution - Monarch had Absolute Power over all Russians & his henchmen took out all outcroping in regions & divide it between all Russians in most equalizing manner. This method helped to go around infavorable weather results in any region, but really dampened any farming successes in all regions around.
Couple of times in Russian History Russian Govenrment tried to leave this weird practice with very bad results. Reforms of Boris Godunov, agricultural Reform of Patriarch Nikon & earlier part of Reforms of Peter the Great, agricultural Reform of Peter III - always ended in great Hungers & regicides or exiling of reformist ruler. Then this practice became Russian custom.
For better management of this practice Russian Government used very archaic structure of Russian country - "Obschina"< that compared Western standard of "early rural military Democracy" of some sort & made Russian Life pretty feudal by its standarts till 60 of XIX century.
Russian Ruler Alexander "freed Russian peasants from their slavery" but couldn't overcame this "Obschina" influence - russian peasants kept their customs of social life - i.e. living in human ant-hills of some sort.
This practice got some sudden support from Russian Government due to fact that 60-70 of XIX century were "hunger years" & Russia began taking credits (from France in first) for improving her food situation, but when in 80 of XIX century "free movement of former peasants" between country & cities was supressed Russia became food-exported herself! This lesson of History didn't go in vain & Russian Government tried to strenghten "Obschina" as hard as possible. But...
Great numbers of Russian peasantry was greatest retarding factor for Russian industry. Then Government needed some source of "free hands" for industry.As result in 80-90 of XIX century Rissia got new Judiciary, Tax & Common codexes that nudged "Obschina" to "push out" their unwanted members to cities. This practice gave so needed source for "human-mills" of Early Industrial Era, but you must take in account that all these people were already "stigmated" as "unwanted" by their rural societies - & gave great army of criminals. Very high criminal level gave some political outcrop in "socialist terror" phenomena in great extent not known in western society. Reason of mass-killing of Nobles by terrorists in these times were high stratifying condition in urban social life. Somebody have got - ALL, but most people had NONE & you must remember that these "most people" was already considered as "criminals" by their rural relatives.
Trying to stop terrorism by dropping "obschina" customs Prime-Minister Stolypin absolve "Obschina" by special Law. This move stopped "Terror" in cities, but raise hunger in country - Russia was between her Revolutions.
Hunger due to "Obschina" absolving & problems with transporting food excess between different region became reasons of collapsing "Holy Russia" & emerging of Soviet Union. But problem remains - when some regions had food excesses & some of them had hunger it's good idea "to take all from peasants & divide food equally". In other case you will get population decrease in one region in one year, but in next year hungered region will get good outcropping with bad outcropping in "full stomach" region of previous year & you'll get total population decrease as result. Then Stalin "collectivization" was returning to usual Russian customs that were usual from XIII century... If you check Soviet History, you will find that after beginning of "collectivization process" Soviet Union never got big hungers due to "bad outcropping" reasons, but before that Great Hungers were usual thing - for example Hungers in Don, Volga Valley & East Ukraina of 20-begin 30 of XX century.
"Collectivization" death sentence was given in end of 30 of XX century. Stalin inderstood that he must prepare his country against possible... "Polish-French-British" aggression with "Germany" as most probable enemy & he must make great nudge to Soviet Industry.
He knew about results of analogical Reforms in 80-90 of XIX century & didn't like idea of high criminal level in cities & returning "Terror" phenomena. (In days of his youth he was "terrorist" himself & knew root of this phenomena & feeding ground of it. Did he need any mad guy throwing bomb in his general direction? I think - not

. )
Then he made step in total different direction: He asked to bring into cities BEST peasants instead of WORST in Czarists times.
It was made by simple differentiation in urban & rural life for soviet citizens in favor to Urban Life with harsh suppresion of "free movement" between country & cities. Every peasant youth could enter Institute or "Technical College" & became urban citizen if he could making his grade. (Difference between Urban & Rural Life in Soviet Union was around 3-5 times!)
It gave present situation with great learning level in modern Russia & really poor situation in agricultural sector. Try to realize that Russian rural populace was consisted from "unwanted people" more then 50 years around - all s,mart or clever guys went out from villages for high level Life in 50-60 of XX century as last...
You couldn't make any sound Economy in agricultural sector if all your rural workers are hereditary drunkards or people with really low IQ. (Any "idealistic peasants" waere really scarce & seldom, then - they were striking minotity

. )
This situation haven't any bind with Collectivization process & if anybody told so - they don't understand Russian/Soviet social Life.
