I've always hated America's almost religious devotion to optimism, so this book had me before I had even cracked the cover. Ehrenreich traces "positive thinking's" course from 19th-century healers through Norman Vincent Peale, prosperity gospel preachers, and pseudo-self-help tomes like 'The Secret'. Makes a compelling case that our refusal to deal with reality and even consider negative outcomes is responsible for many of our current problems.
