The world is becoming a better place. It is not utopia. We are not without substantial challenges. But we are becoming (as in movement along a trajectory) better (as in measurably improved according to a standard.)
The Human Development Index is a United Nations measure of well-being combing data about income, literacy, education, and life expectancy. Here is the index for the nations of the world in 1980 and then in 2012. The reality is that we are living through the most astonishing transformation toward human well-being in all of history. You can find the interactive version of the chart at Our Data.
