Dangerous Thoughts is a collection of Gary Jason's most popular and provocative articles from newspapers and political magazines, nearly three hundred in all. A few of these were published as far back as the later 1970s, but most of them are of recent vintage. There are eight broad topics the articles cover, and are gathered together in chapters accordingly. The first is school reform, and the critical need for school choice. The second is environmentalism and its negative impact on rational energy policy. The third is demographic change the continuing need for immigrants (legal, and within reasonable limits). The fourth centers around the continuing need for free trade. The fifth is the need for entitlement program reform. The sixth is the need for various political reforms, and the seventh various economic ones. The eighth is the divide between intellectual elites and ordinary citizens. A final chapter includes various miscellaneous pieces.
