When we think about global trends, we tend to focus on their importance and how rapidly things are changing. China’s economic rise, along with massive economic development and urbanization around the world, all have unambiguous importance, though we will endlessly disagree about how they will interact and few of us will live long enough to feel confident we saw the final outcome (there are major limits to knowledge and prediction).
If one makes a sincere effort to understand what is happening in the world and feels compelled to try to encourage some of the best possible outcomes, given the state of the world right now, perhaps it makes sense to think in terms of which trends you hope to speed up and which you hope to inhibit.
The key question in effectiveness has to be: am I / are we making a difference in terms of an important objective.
So perhaps it makes sense to think about being a catalyst or accelerant (to choose a more obviously violent analogy) hoping to create as substantial a ∆ifference as possible in the final chemical equilibrium.
