When you think of economic globalization, you think of the integration of national economies into the international economy through trade, foreign direct investment, capital flows, and the spread of technology. But one very important one that isn't thought of too much is migration. In the past it was almost unthinkable to leave your homeland just for a job overseas, especially just to look for one. Now it is becoming commonplace, especially with the high unemployment rates seen in countries such as the United States, United Kingdom, and Spain (the latter of which is a whopping 19.9 percent!). Meanwhile in other developing economies, especially in Asia, the rates area much more respectable. The unemployment rate in Hong Kong is 4.6 percent, in Australia 5.1, and in Singapore only 2.2 percent of the people are out of work.
