The Space Merchants (S.F. MASTERWORKS)
Pohl has this knack of making sci-fi (even sci-fi with big ideas) roll along quickly and hilariously. Space Merchants is about an ad exec convincing people to move to glorious unspoilt Venus -- which is a hell-hole. And it's jam-packed with ideas: Conservationists who are treated as subversive because they disrupt capitalism; "Chicken Little" machine food; overcrowded cities. But these are all backgrounded to a cracking story about, well, the advertising industry.
