I've really enjoyed multiple Michael Lewis books, and especially found him likeable and very smart when he came to Microsoft many years ago to speak about the book that he'd recently gotten published. I count "The Undoing Project" as one of my top ten most enjoyable books to read. This book, however, let me down. There is nothing that Lewis did wrong, nothing about his writing that sucked, nothing promised that wasn't delivered. The truth is, I didn't "read the fine print" before buying this book. I assumed, and everyone knows what happens when you assume. Had I known that this book contains the full text of various economists, and that Lewis's own writing on those texts and their respective authors constitutes a very small fraction of the page count, I would have checked it out from the library instead. I'm old enough that I have to economize my time reading and I don't want to read the entire magnum opus of Keynes. I wanted to get Lewis's take on all these classics, and felt that I got an appetizer rather than an entree for each. So, three stars because there is far too little Lewis, which I suppose is a very positive negative review.
