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. It's not unusual to go to the poorest places on earth and find a small
cadre of people who aren't poor at all. Sometimes, this is an unearned position, one that's inherited or acquired in ways that take advantage of others. Regardless, you can't just announce you're an elite and become one.
In more and more societies, though (including my country and probably yours [and I'm including virtually the entire planet here, except perhaps North Korea] ), 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).
Perhaps I'm flattering myself (and you) but I think almost everyone who reads blogs like this one is part of the elites. It's not because of birth or financial standing, it's because of a choice, the decision to be aware and engaged, to challenge a status quo of your choice.
The number of self-selected elites is skyrocketing. Part of this is a function of our ability to make a living without working 14 hours a day in a sweatshop, but part of it is the ease with which it's possible to find and connect with other elites.
The challenge of our time may be to build organizations and platforms that engage and coordinate the elites, wherever they are. After all, this is where change and productivity come from.
Once you identify this as your mission, you save a lot of time and frustration in your outreach. If someone doesn't choose to be part of the elites, it's unclear to me that you can persuade them to change their mind. On the other hand, the cycle of discovery and engagement and shipping the elites have started is going to accelerate over time, and you have all the tools necessary to be part of it–to lead it, in fact.
