In the developing world, there's often a sharp dividing line between the elites and everyone else. The elites have money and/or an advanced education. In more and more societies, though, I'd argue that there's a different dividing line. This is the line between people who are actively engaged in new ideas, actively seeking out change, actively engaging--and people who accept what's given and slog along. It starts in school, of course, and then the difference accelerates as we get older. Some people make the effort to encounter new challenges or to grapple with things they disagree with. They seek out new people and new opportunities and relish the discomfort that comes from being challenged to grow (and challenging others to do the same).
