It's a pretty amazing book: First he explains in terms accessible to all various macroeconomic aspects, the limits of the various models used in the past, and clearly states the current limits of economic science (and science social in general). At the same time, I think this book is at the forefront of what science has to offer to policy makers, whether of the right or left, to enable them to base their decisions (in particular, in removing some economic dogmas). Furthermore, there is a whole scientific modesty that I like very much in the analysis of Thomas Piketty. He never presents the "truth", but theories experimentally better founded than the previous ones and which are intended to be enriched thereafter.
