I first read this book twenty years ago and have just re-read it. It was written in the early fifties and describes what could arguably be described as the inevitable consequences for society of capitalism. Frederick Pohl, having been an advertising copywriter, writes in a simple style which suits his subject matter perfectly. Basically, the advertising agencies rule the world - 2 advertising agencies to be precise. In order to be a part of society, and there is enormous pressure to be so, you have to be a "good consumer" - buying and becoming addicted to whatever the agencies sell to you. The "baddies" are the consies - conservationists who endeavour to fight this most terrifying system where wood is the most valuable commodity as there is hardly any left. I have often thought what a good film this would make, but then having read the book again I realise that nobody in our 'system' would be brave enough! I can't recommend this book highly enough.
