re: Specialization and Globalization
Ok. Globalization creates wealth. But like I said, unless you are willing to relocate anywhere in the world, you're career choices will be limited. But national borders still exist, rules and cultures still differ, and that dream job you always wanted might be inaccessibly located, due to language or legal or cultural borders in some country that isn't even democratic. Migration is kinda risky. Look how our own countries treat immigrants: they may work in low-paying factory jobs for their whole lives just because they have an unintelligible accent or a different skin color than management, or have wierd beliefs.
Good luck with that.
