Keynes cannot be anything but “misunderstood.” His writing is very poor. I have tried several times to read Theory of Money...etc and cannot make of sense out of it. Paragraphs do not hang together. His arguments do not fit his assertions. What people “understand” about Keynes is the official interpretation of his book and the things he later said he wrote. His writing simply does not make sense. Everyone should find a copy of the book and read it. Read it carefully. If you just skim the lead sentences in the paragraphs and go straight to the conclusions you may feel you know what it is all about. If you analyze it it becomes simply turgid and irrational ramblings
I tried that book as well and found it unreadable. The official interpretation you speak of comes from Paul Samuelson and John Hicks. They must have had magic spectacles to decode Keynes’ writing or they got his ideas from some other source.
