It seems that not many people realize that the world hasn't become just interconnected with the raise of the Internet, and truly global media. Trade has managed linked the economies of many countries so tightly together, that they need each other for their continued growth.
Borders are losing their current meaning each day with the flow of goods, ideas, and information. In many ways, borders are becoming just a geographic reference to place the point the origin, or where a product is consumed. As time goes by, more people are seeing themselves not only as a citizen from a certain country, but as part of something bigger.
While they jury is still out on what will all this ultimately mean to humanity at large, so far it seems that we will be able to make it work for the better since there are more people actually working to make it so. So much so, that trying to stop this global may prove to be impossible since the benefits of making it happen seem to out wight the pains of growing into a global community.
And to be honest, its on our best interest to make sure that the people take control of it in order to make it work in a way that benefits most of us. I don't see local identities being completely lost, since its important to know our root. Yet, the free flow of people around the world will become a given, just as the free flow of ideas have become a norm.
The most important thing for me, is that we need to have people being able to freely move around the whole world in order to actually make a better world possible. Only when people are able to come together freely, we can hope to build a something better.
