I read it like 6 years ago. It's really good as a reference, I've got a couple of acquaintances that studied economics in university and I still pick it up ocassionally to lift arguments and plots when I'm talking to them. My acquaintances are full-on neolibs or keynesians, and I think that book is a large part of why they keep messaging me and considering what I say.

The purpose of the book according to its author was to compare the established schools of economics with the "Marxian" school, and I think it succeeds. However, it means it spends most of its length carefully developing theories that are later shown not to fit very well to empirical data, or that are simply unfalsifiable.

Anwar tried to uniformize the notation across his entire work, so you still need to have an Capital and econ textbook around to convert his weird notation to what everyone else uses.

Other books on that line that I read around that time and stayed with me were Cottrell and Cockshott's "Classical Econophysics", Farjoun and Machover's "Laws of Chaos", and Stafford Beer's "Designing Freedom"
