Before Europeans arrived, North America had supported human communities for 12,000 years. In the 235 years since the Declaration of Independence, the U.S. population has gone well over 300 million and we use natural resources at a rate unequaled in the world. Our economy is declining, our foreign indebtedness is growing, and we send hundreds of billions of dollars abroad each year to buy oil. Are we already living on borrowed time? Regaining control of our future will require long-term rational policies to which neither of our political parties are committed. Supply-siders and their fellow travelers have turned economics on its head. We need to get back to policies that will restore prosperity. The author lays out the keys to addressing our economic weakness and the challenges in energy, education, and poverty. He also proposes an approach we can follow to maintain our influence in a changed world.
