I don't know much about totalitarian dictatorships. I know that communists think of capitalism as having two classes and that the only way to resolve conflict between them is revolution.
Yeah.  It's running pretty rampant in China and deals with 2 classes that are the root of all problems in society that will ultimately be solved through a revolution
What do you think about the Bolshevik Revolution? I really don't know much about the Bolshevik Revolution but I know Communism had a  common ownership by production with absence of social classes That's true. A lot of people liken it to totalitarian dictatorships, though.
All of these share the analysis that the current order of society stems from its economic system, capitalism; that in this system there are two major social classes: the working class—who must work to survive and who make up the majority within society—and the capitalist class—a minority who derives profit from employing the working class, through private ownership of the means of production—and that conflict between these two classes is the root of all problems in society and will ultimately be resolved through a revolution.
