I mistakenly thought this was going to be an economics centric book but it is in fact mostly focused on Capitalisms effect on the climate crises. 2/3rds to 4/5ths of the book are Saitō’s explanations of exactly how Capitalism contributes to the crises and how our current plans to combat the crises while maintaining a capitalist society (such as the Green New Deal, EVs, etc.) will not be successful. Most of this knowledge is already common amongst those who would be interested in these type books; Saitō’s unique perspective is his claim that Marx and his philosophy have been wildly misunderstood and practiced throughout history and that his true aims, Degrowth Communism, is the way to avoid the end of humanity. While his climate science is solid, and his end goals sensible, the methods he proposes of bringing about degrowth communism leave a lot of unanswered questions. One example is his insistence that in this type society unnecessary products will not be made, but he keeps very vague about what exactly is unnecessary. I’ll stop here as the rabbit hole of questions opens very quickly. The conversation he is starting should be had, but it is a much more complex conversation than the less than 300 pages of the book is able to dedicate to it. Honestly, I could have read a wikipedia article on his ideas and left just as informed.
