The Smart Society offers a detailed blueprint for how the United States can recast its human capital policies to make all Americans-not just a privileged elite-smarter and more successful than ever before, at the same time stemming the size and cost of the nation’s safety net. The spectacular, centuries-long success of the United States is based on its having determined, early on, to be a smart country, single-mindedly developing institutions and practices that enabled its native born citizens to maximize their economic and social potential, and welcoming opportunity-seeking foreigners to join them. Over the last four decades, however, the vaunted United States human capital machine has been breaking down, dimming the economic and social prospects of millions of Americans. If The Smart Society blueprint is followed, these trends can be reversed and the nation and its people can quickly regain their preeminence in the hyper-competitive and globalized world of the 21st century. This is a most topical issue today because the country’s current heated political disagreements are not just about the proper size of government, but about how the United States can reverse its apparent decline and restore its historic economic and social vigor-in other words, regain its place as the world’s smartest nation.
