One of the aspects of globalization that I talk about briefly in the book (in chapter 9) is the fact that so many people are moving out of their countries of origin, whether as economic migrants seeking a better life or as political refugees fleeing from oppression.
A 2005 UN study estimated that approximately 191 million people were living outside or the country in which they were born. If all those people were herded together into one country, they would make up the sixth largest country in the world by population, behind Brazil and ahead of Pakistan.
The small state of Eritrea illustrates the problems when people want to leave their country. Recently 12 members of their national soccer team disappeared after playing a match in Kenya and losing 4-0. (If they had won, would they have felt better about staying?)
Migration is a serious and often overlooked aspect of globalization, which is the process of increasing interconnection between peoples. People are moving around all over the world, for all kinds of reasons. Let's hope these guys from Eritrea can be united with their families some day (if they ever turn up).
