Need to throw out a recommendation for this book:
You will find it among the science fiction books, but there are no traditional sci-fi elements to speak of. This is a satire of a completely deregulated market, consumer addiction, and a powerless government. It is a bit predictable and even silly at times but a fun, fun read. I don't want to give anything away; if you've enjoyed the traditional dystopias - 1984, Brave New World, etc. - this is a fresh spin in that field.
Or, also, if you hate libertarians, you'll probably like this.
