I just finished reading Piketty's book and I'll soon post some of my thoughts on it. For now, I just wanted to share the last few sentences of the book. Whatever you think of Piketty's work, I think this passage is nicely written and will resonate with members of this forum:
"...it seems to me that all social scientists, all journalists and commentators, all activists in the unions and in politics of whatever stripe, and especially all citizens, should take a serious interest in money, its measurement, the facts surrounding it, and its history. Those who have a lot of it never fail to defend their interests. Refusing to deal with numbers rarely serves the interests of the least well-off" (p. 577).
