The aim of this book is to inspire a better politics: one that will enable future generations to be happier. Greater well-being and better health should be the goals, rather than wealth maximization. We need to value healthcare more than hedge funds, caring above careers, relationships more than real estate. The book is about what makes most of us happier, but it is also about the collective good. We cannot truly be happy if those around us are not happy. The evidence for a successful politics that would promote happiness and health is examined, and policies that take account of this evidence are suggested. Government can and should work to make us happier.
