I really love this genre of books that makes economics seem human; it was such darned deadening subject when I studied it in high school. And this book may well be the first of the human economics genre, though I prefer Malcolm Gladwell and Dan Arielly (perhaps because I read them first). In any case, this was a fast and absorbing read, especially the section about crack dealers. The point about abortion and crime is so well-argued, I don't think I can deny it. . .except that it's morally appalling. But the book fell down for me at the parenting chapters. The abortion argument states that children who are wanted by their parents have the best futures ahead of them. So how can the author then argue that parenting style just doesn't matter that much? But despite that, I enjoyed the book and have already started on the "sequel."
