Interesting but not groundbreaking book on consumerism as identity creation. I think James Twitchell covers this area better, but still, a tasty read anyway. In fact, Walker spent quite a lot of time quoting Twitchell and Paco Underhill, which I guess is inevitable when crossing such well travelled territory.
Walker did delve a little more into some kind of underground/pseudounderground consumer niches, like the sneaker freaks, etc, and the influence these subgroups have is pretty incredible. Still, it was nothing I hadn't read or known before. I guess I wouldn't really pass it on to a friend who I thought would be interested in this stuff- I would, however, recommend Twitchell's Living It Up: Our Love Affair With Luxury and his Lead Us Into Temptation: The Triumph of American Materialism without hesitation.
