Power has always changed hands, Toffler points out, but only at a few points in history has the very nature of power itself shifted. The hidden powershift of our era is the shift from muscle and money to mind as the primary lever of social control. Outlining today's "new system of wealth creation", Toffler shows why knowledge about knowledge has become the critical factor in daily life, business, politics, even in war. "Powershift" describes today's "info-wars" that pit managers against stockholders, retailers against manufacturers, the United States against its allies, and partisans of perestroika against the Soviet bureaucracy. The century's end will be dominated by intensifying battles to control information, knowledge, and the media.
