This author holds Marxism to be dead as an analytical framework. In particular, he stresses the various failures of Marxist class theory pointed out by Konkin and others. After a thoroughly researched dive into the myriad approaches to class analysis throughout history, Konkin’s work is expanded upon and an agorist class theory is developed as a replacement. Found it very intriguing and will definitely revisit.
Some parapgraphs were valuable, some not. It's a short text so it was not a waste of time. However, the text is mostly quotation of another author, SEK3 (not that anything to the contrary is claimed by the author of this text though).
