People are getting not just healthier, richer, and safer but freer. Two centuries ago a handful of countries, embracing one percent of the world’s people, were democratic; today, two-thirds of the world’s countries, embracing two-thirds of its people, are. Not long ago half the world’s countries had laws that discriminated against racial minorities; today more countries have policies that favor their minorities than policies that discriminate against them. At the turn of the 20th century, women could vote in just one country; today they can vote in every country where men can vote save one.
