From the interview:
If you look at life expectancy, it has shot up worldwide. If you look at child mortality, the number of kids that die before the age of five is going down in every country; it’s been halved worldwide over the last 20 years. The number of people in school, the number of people learning has been going up. The number of people dying in murders has been dropping.... Measures of anything almost apart from the environment... is just in the right direction worldwide. And improvement has been faster in the countries that were furthest behind.
