What exactly did they "do about the Landlords" other than murdering middle class landlords in favor of an inescapable Fedal Lord that is the Communist State?
Hiding much or all of the rent on the balance sheet of the State, while paying prison wages for mostly-compelled work and making people live on the edge of resource starvation, is simply barely hidden feudalism and even slavery.
Where is the people's Government, exactly? All communist governments are only extreme charicatures of Feudalist Lords, free to engage in the worst excesses over people who they demand not only be slaves but give into psychological enslavement. Communism is psychological feudalism, in addition to physical. At least medieval Serfs were free to openly dream of something better.
Communism is a Three-Card Monte psychological trick that creates Feudal Lords in the Upper Ranks of the State, and abuses the Serf into seeing Serfdom as the most virtuous lifestyle.
It's not a deep mystery as to why many upper class psychopaths like communism. It seeks to neutralize a lot of feudalist inconveniences, mostly with an origin in the otherwise free mind of the Serf.
