George Gilder proposes a bold new theory on how capitalism produces wealth and how our economy can regain its vitality and growth. Gilder breaks away from the supply-side model of economics to present a new economic paradigm: the epic conflict between the knowledge of entrepreneurs on one side, the blunt power of government on the other. The knowledge of entrepreneurs and their freedom to share and use that knowledge are the sparks that light up the economy and set its gears in motion. The power of government to regulate, stifle, manipulate, subsidize, or suppress knowledge and ideas is the inertia that slows those gears down or keeps them from turning at all. One of the twentieth century's defining economic minds has returned with a new philosophy to carry us into the twenty-first.
