I will only say here of the Piketty book that practically almost absolutely everybody is talking about: it really is that good. I’m most of the way through it, hopefully to finish today. It’s just … hard to call it anything short of a landmark. It consolidates everything you’ve read or thought about inequality into a single work, complete with analytical support for nearly everything (though oddly lacking citations in nearly all of its footnotes).
This is just a downpayment on a review. You really want to read the book, though.
