This book is a general interest book- and it certainly is interesting. The book, for anyone looking for an entertaining read, will like it. In a nutshell, the book takes a look at all sorts of things in society, from crack gangs to parenting, and then attempts to make sense of them by applying econonmic principles. According to the book, economics is really the study of incentives, and so using this kind of angle, the book comes up with answers to why things work the way they do.
A book that's hard to put down, I'm sure many readers will enjoy it. Also recommend The Sixty-Second Motivator
for a more simplistic explanation of what motivates people and gives them incentives to do what they do.
