See now there you've made a crucial error. You're recommending a book which, while it has some criticism of the specifics of how the USSR implemented socialism, on the whole it's quite positive about the idea of establishing a dictatorship of the proletariat in general. Obviously that disagrees with my preconceived notion that humans are greedy, and that therefore capitalism is good, so I would never read a source that contradicts this, because I would have to dismiss most of it outright. And that's just a hassle.
