I liked this one, even though the facts I've heard they not really new to me or impressive or anything. The structure is good and the author writes a bit about history, and a bit about biology, sociology, etc.
What I really liked is the explanation of this economic notion — the pie that keeps bigger when everyone's trying to get their own portion. I definitely heard this metaphor before but didn't really understand it. And now I think I do.
4/5.
