Here is an unscientific explanation. NA and EU are populated by older souls: some of them see the value of giving, while others, who've chosen the wrong path, are adepts at scheming; but both are similar in their maturity. The less mature souls are still busy with mastering their emotions and their nations are too chaotic for this reason: they either fall apart without a leader, or when a mature leader presents itself, they have to be ruled by an iron fist (China, India). Eventually the focus will shift to another place on Earth: the most advanced will move on there and America will join the long list of empires that were once great, but that event is still a thousand years away.
