I've been listening to my Capital audiobook while driving a truck for my job. This book is hard and dense to listen to as an audiobook, especially for me as I tend to daydream. It's essentially listening to Marx explain his economic theories as mathematical proofs. I'm going to have to read it on paper at some point.
I wonder why there are so many sects from Marx's work, though. Lenin had the right idea. Marx was bashing on reformists, "trots", and bougie economists across his work, and a couple hundred years later a lot of people still believe there's any chance of doing anything short of revolution.
