I don't want to give a star rating for this, as I didn't finish it so it seems a little unfair. But in spite of generally agreeing with the idea of Affluenza (have read similar books by Hamilton/Dennis and one based on a US tv series), I just didn't like the author's style.
He quotes statistics, but then draws unsupported conclusions from them. I felt like writing "correlation doesn't equal causation!" in the margins every time he made sweeping generalisations based on anecdotes or tiny details of a larger statistical area. And I felt that he had very little sympathy for the people he interviewed for the anecdotes, even though he thought their problems came from their upbringing.
Given that I've got a huge to-read list right now, I decided to cut my losses and move on. Other people may feel differently about it, and I hope they get something of value from reading this book.
