Globalization and specialization related

Globalization is the world becoming more integrated, via their economies, and recently via ease of transportation (airplanes). Specialization was in the Mesopotamian area at the first with people working on different jobs to sort of 'trade jobs' for example the pottery man would give pottery to the guy who built houses etc etc. In Globalization, this works extremely well, for people on the other side of the world could be making chocolate in exchange for technology from people who do that. And so you have people all over the world specializing in things to provide for other people across the world in exchange for goods. This is all done through the money system.
