He says in the beginning that in building the USSR Stalin shouldn't be idolized or mystified as a great man but then proceeds to lay the post-war failures directly at his feet. If he really thinks that the communist party became bourgeoise because they didn't want "real jobs" then that is an implicit statement that the vangaurd party is always doomed to fail to lead the dictatorship of the proletariat.
I don't want to get into the habit of psychoanalyzing people but, if we accept that history is as much a reflection of the present as a record of the past, I'd say that alternative histories such as this are more a reflection of their author than the material conditions at the time. Matt is bourg-ified and doesn't want to work a "real job" and is projecting his anxieties about his own material conditions onto a totally different circumstance.
I would highly recommend the book Elementary Principles of Philosophy by Georges Politzer which you can find for free on the Foreign Languages Press website under foundations. It is an introduction written for a general audience that will give you a solid base from which to approach other philosophical texts. I'd also really recommend getting a solid grasp of dialectical and historical materialism before trying to dive into other philosophies. Marx laid out the foundations of a scientific approach to understanding the world in all of its aspects. If you understand how to analyze things through a Marxist lens you will be able to cut through a lot of bourgeoise, metaphysical, idealist etc. philosophy which is interesting historically but otherwise useless, or even harmful, if used as a basis for practice.
