To behold this graph is to apprehend human progress at a glance. And packed into the lines are two vital subplots. One is that although the world remains highly unequal, every region has been improving, and the worst-off parts of the world today are better off than the best-off parts not long ago.45 (If we divide the world into the West and the Rest, we find that the Rest in 2007 had reached the level of the West in 1950.) The other is that while almost every indicator of human well-being correlates with wealth, the lines don’t just reflect a wealthier world: longevity, health, and knowledge have increased even in many of the times and places where wealth has not.46 The fact that all aspects of human flourishing tend to improve over the long run even when they are not in perfect sync vindicates the idea that there is such a thing as progress.
