Basic run-down at what you're looking at:
The Russian aristocracy owned the land and peasants working on it. The tsar could not keep the peasant revolts in check anymore so he abolished serfdom (a system very similar to slavery) but the land still belonged to the nobility. The nobles now had land but no one to work on it. so they offered the peasants to work for pay, and the option to buy land for themselves. The smartest and most hardworking did so.
After the Russian Empire capitulated to Germany in 1917, the (((Communists))), mainly composed of (((upper-middle class intelligista))), instigated a violent revolt. After the first democratic elections, they received fairly little support. Lenin, who blamed all of Russia's problems on the kulaks (well-off peasants), ordered the Communist secret police, the Cheka, to round up the kulaks and either shoot them or to send them to Siberian slave camps.
There was absolutely nothing justified in what the Commies did. The so-called "right-wing feudalist rich'' had been forced give up most of heir privileges in the 60 years since serfdom was abolished. Russia was on the track for Western style democracy, until the Communists put a violent end to it and instituted one of the most brutal totalitarian regimes in history.
Anyone who tries to refute this with some other bullshit answer or revisionist explanation should look into other historical sources other than the cliff notes from Professor Goldbergsixgorrillionstein's lectures from Anyfuckhead Cangetadegree (((College))).
