First, it was quite obvious that the author has some sort of animus against non-materialism, since he seems to glory in taking gratuitous chops at environmentalists, the voluntary simplicity movement, and pretty much anyone who doesn't agree with him. I was thoroughly sick of it by the end of the first chapter.
Second, he does not back up many of his assertions, despite a plethora of footnotes. For instance, he asserts that kitchens have gotten smaller in the last few decades (seemingly as a way of proving that we eat more take out and less home cooked food), without stating whether he means suburban or urban kitchens, new construction or remodelling, apartment, condo or detached kitchens...you get the picture. There are similarly unsupported assertions about trash disposal, landfills, and teenage buying patterns.
Finally, it was *dull*. The only parts that were even vaguely entertaining were the last few chapters, when the polemics were replaced by personal reporting of his trip to a mall. I learned very little about American materialism, and far more than I wished about the author's political biases.
A huge disappointment.
