“Globalization” is a word invented by historians to describe the increasingly interdependent relationship of cultures and nations all over the world. If a factory opens or closes in Japan, the impact is felt by American workers, and vice versa. More and more, our economies rise together and fall together. No nation can stand alone any more.

Globalization results from rapid transportation and instant communication. Centuries ago, when transportation was slow and messages were carried by hand, various cultures could remain distinct, unaffected by others. A few Italians visited China, and a few Chinese visited Italy, but most people never traveled far from their homes. Even two thousand years ago Chinese silk was available in Italy and Italian glass was available in China, but both were very expensive because of the number of merchants who had bought and sold these items and the number of governments who had taxed these items as they traveled.

Globalization is good because we can learn about other people and experience their culture without leaving our homes. Purchased recordings, television, and the internet expose us to music and drama and other forms of art from nearly every culture in the world. Japanese music is performed in Vienna, and the works of Mozart are performed in Tokyo. One old warehouse downtown has been transformed into an eating establishment with a dozen booths selling food. Customers choose from cheeseburgers, pizza, gyros, tacos, Japanese food, Thai food, Indian food, and soul food. Moreover, economic links reduce violent confrontations between nations. Until 2008 (when Russia attacked Georgia) there had never been a war between two nations that both contained McDonald’s restaurants.

One risk of globalization is homogenization of culture. When every city in the world has McDonald’s and Walmart, will local cultures survive? If you were blindfolded and transported to a shopping mall somewhere in the United States, could you guess what city you were in by looking in the various stores? Perhaps the caps and T-shirts in the sporting goods department might give you a hint, but even there you will spot Cubs hats and Yankees hats and Dodgers hats in every part of the country.

Globalization makes it harder to “buy American” in the United States, to quote a movement from the 1970s and 1980s. Most carmakers have headquarters in several countries and are owned by major stockholders in several countries. They have parts factories and assembly factories in various countries. Hours of research would be needed to choose a make and model of car and determine how much it was “made in America.”

When a company based in the United States builds a factory in Mexico, they are hoping to reduce their expenses to increase their profit. However, they are also hoping to pass some of the savings to their customers, beating the competition with their better prices. At the same time, by providing paychecks to Mexican workers, they are increasing the likelihood that more products “made in America” will be bought in Mexico, which increases jobs or enlarges paychecks in the United States.

Globalization is complicated. No easy answers exist for the problems it causes, and those problems are offset in many ways by the benefits of globalization. As long as travel remains rapid and communication remains instant, globalization is unavoidable. The best we can do is work to preserve local customs and manners while we enjoy the fact that nothing is truly local any more—everything is international. J.
