答案                         We’re Living the Dream!
    Americans enjoy longer, healthier lives in more stable families and communities than we did 20 years ago. But other than the crime trends, these facts are rarely reported or shared via word-of-mouth channels. Many Americans, for instance, are convinced that "half of all marriages end in divorce," though that hasn’t been the case since the early 1980s, when divorce rates peaked at just over 50%. Since then, they have declined by almost a third.
    This is not merely a story of success in advanced industrial countries. The quality-of-life and civic health trends in the developing world are even more dramatic. Even though the world’s population has doubled over the past 50 years, the percentage living in poverty has declined by 50% over that period. Infant mortality and life expectancy have improved by more than 40% in Latin America since the early 1990s. No country in history has improved its average standard of living faster than China has over the past two decades.
