If you ever begin to feel complacent in life and need a reason to feel guilty, just pick up Affluenza by John De Graaf*. It's not just a book, as it was a PBS documentary before the first edition was printed. I picked up the second edition guilt-free, since somebody gave it to my wife and I to read. We're just trying to make the authors proud. We may even see if we can share the wealth.
The book is not that guilt inducing, unless you have some serious problems. If you have those problems, you probably aren't likely to pick up the book. Even if that's the case, I think it's worth reading. The authors do a decent job of getting their message of decreasing consumption and unnecessary purchases without being overly preachy. The text was easy to follow, making the book easy to digest. Their facts seemed to be in order, though I do question their use of some of their data. It's not one thing in particular, but I perceive with books like this, it's easy to cherry-pick data to support the author's already established conclusions. While I don't have a specific instance, the tone of the book did fit that bill. It's not unusual, since this is not an academic book. It is worth noting. I think that the general conclusions and ideas in the book are reasonable and worth considering.
I liked that the book spent time referencing two other books I own, Culture Jam by Kalle Lasn and Your Money or Your Life by Joe Dominguez and Vicki Robin. Both books center around living simply or at least by minimizing the unnecessary distractions of stuff. Both are worth reading as well, though I would chose Your Money or Your Life first as it's the first personal finance book I've read that actually focuses on making real changes to spending habits. Affluenza pulls from these books effectively and provides a fair endorsement of them.
The one thing that bothered me about the book was their little survey to show how bad your affluenza was. And no, I did not score poorly. I landed in the second group of only being mildly infected. While the authors admit the survey was not scientific by any means, it was a little dorky. Some of the items included on the list didn't work for me, like whether you eat meat once a day, or if you've ever experienced road rage, or do you ignore the mpg of your car. Then there was the scoring system. You were scored out of 100, but there were 50 questions and each question counted as two point. Why not just make the scale 50 or score some questions as more if you aren't going to use the 50-point scale.
On the whole, the book is a good read, but I think that it might be worth it to find the documentary it's based on as well. I have not seen it, but a portion of it is shown below.
* The book as three authors: John De Graaf, David Wann, and Thomas H. Naylor. For space and sanity I will refer to De Graaf as the only author.
