People act differently as a whole than they would as individuals. Mass movements demonstrate certain general features depending on their underlying basic ideas: rational following reasonable principles, or irrational following an emotional and unreasonable path. Mass movements may work within existing norms of social boundaries and institutions, or discard all norms and institutions reversing direction, a complete reversal of values. In this book, the author examines the American managed care system, a supposed “revolution,” as compared to the behavior of other historical mass movements. By studying the background, development, and implementation of the mass movement into managed care, and the characters involved, we can understand its history, judge its probable course, and anticipate its outcome.
