I tried talking about this in an earlier draft of my article but found it to be a deep rabbit hole. I'd like to explore this more fully in a future post. I feel that will be more divisive in it's reception :-)
If you take this task you have to do an incredibly deep dive of China vs USA. The US is the global leader primarily because of this focus on the individual and individual achievement. European countries compare somewhat poorly as they're sort of focused on the individual but with huge dollops of government support/intervention. China however is completely unapologetic in its team driven focus and now has significant success to back up that this method can work. I'd be interested in someone who can contrast/compare there.
You have fallen into the trap a little ;) what does it mean to be a global keader? What are the true goals? Scrrr's comment was discussing happiness. Neither China nor the US do nationwide happiness surveys AFAIK.
