What does globalization mean for government? Nationality?

As the world continues to follow the trend of flattening that Friedman discusses in his book, we must ask what the role of government will become in the increasingly flat world. Will it become more or less important than it is now? Or will it change in a way that we cannot even yet anticipate?
In an article titled "The Benefits of Globalization," the CATO Institute claims that "While globalization may confront government officials with more difficult choices, the result for their citizens is greater individual freedom. In this sense, globalization acts as a check on governmental power that makes it more difficult for governments to abuse the freedom and property of their citizens." Because of this, it is easy to see how globalization and government may be able to work hand in hand. Globalization will soon be forcing government to not only do the job it was intended to do, but also perhaps become better and more consciencious about it.
An article titled "Globalization Requires Positive Government Policy Responses" summarizes the key points and analyzes a book by Dani Rodrik, who points out three sources of tension between the global market and social stability. This article claims that "...Each of these points...reveals an important weakness in how advanced societies are currently handling—or are equipped to handle—the consequences of globalization. Collectively, they point to perhaps the greatest risk of all: that the cumulative consequence of these tensions will be new class divisions between those who prosper in the globalized economy and those who do not, between those who share its values and those who would rather not, and between those who can diversify away its risks and those who cannot. Rodrik warns that this deepening of social fissures harms all sectors of society, including the winners from globalization because of the threat they pose to the continuation of the process."
This is an important thing for us to take into consideration. How prepared are we for globalization and the consequences that it could bring? As individuals, we may think we are prepared, but when we think about society as a whole, there may be many weaknesses in our preparation. But no matter how prepared we may be, globalization, even though it is in a sense bringing together the world technologically, is at the same time isolating different people and groups of people who have different beliefs about the way things are changing. The theme of globalization and everything that it brings and creates can tend to become quite controversial, and it makes sense that people who supported it would be divided from the people who don't want to see it happen. In this way, globalization could separate us as a society and a culture more than it brings us together in other ways. The question arises: What will things such as nationality mean in a completely globalized world? In a part of his book, Friedman talks about a businessman's experience at a hotel. When he asks if entertainment is available on the television in his room, the hotel clerk simply tells him that "every room has every movie ever made in every language, anytime, day or night." This seems to be becoming the norm anywhere you go. No matter what country you are in, you can probably find some people who speak English. I myself traveled to Italy my senior year of high school, and in every store or restaurant I went to, I interacted with an Italian who spoke English fluently. It was expected that the people who came to these places would know English, so most people didn't even bother to ask if I spoke Italian before they started talking to me in English. It seems as though this is the way the whole world is becoming. Many years ago, if you traveled to or spoke with someone from a different country, a language and culture barrier may stand in the way of successful communication. Now, it seems as though with globalization, the world is becoming "Americanized" and different countries are losing their own unique, individual culture. In the beginning of The World Is Flat, Friedman mentions companies in India that deal with customer service, talking on the phone to people in America offering support for different things, like computers, telephone services, etc. Before they can start working, these Indians must take classes on speaking without their accents. Things like this, if we aren't careful, will likely someday eliminate all traces of different world cultures. You can already go to a McDonald's in just about any country you travel to, and do so many other things that feel American. Because of things like this, all of the cultures of the world will someday mesh into one giant culture. Nationality, country, and culture will no longer matter. All of this will be wiped away with globalization.
