The more successful regions in today's world seem to be the ones that are more united than other regions. Chinese civilization is united, apart from Taiwan, Singapore, and the overseas Chinese. The Indian subcontinent is (approx) 75% united into the nation of India, the rest splintered between Pakistan, Bangladesh, Nepal, etc. Europe is more divided, but because there were 4 approx equal countries (60 million people in each of West Germany, France, UK, & Italy), they federated easily. North America is mainly the US, easily controlling Canada (and Australia/NZ). South America is 50% Brazil, so they can successfully electioneer in the "South American Union". The Muslim world is more divided, with a few equally sized players (Egypt, Turkey, Saudi, & Iran) who won't ever federate because of religion and foreign interference. And sub-Saharan Africa is the most divided of all. Unity and modern success seem to be correlated, though of course not necessarily one causing the other.
