Although the English language has become globalized and dominant in the modern era, just knowing English as the only language is equivalent to a disadvantage in a world of globalization, multilateralism and multipolarization, while also taking away a chance for one to better understand the world of different cultures, and a chance to develop a better ability to think.

To start, it is important to acknowledge the power of the English in connecting the world together in at least the past century and it has advanced the world. During the time of the dominance of English, which also represents the dominant of the United States, an English-speaking country, the world has seen significant development humanity has ever seen across various fields. It is "the language of science, commerce, global politics, aviation, popular music and, above all, the internet" (Source B). The reach of the English language resembles the completion of the Tower of Babel, with the ultimate goal of uniting all people with a common understanding and toward a great future of human progress. It is safe to say in the twentieth century, people have found themselves such a powerful language to establish such a dream. Since the English language is able to provide so much to the world, and to the speakers themselves, people wonder what is the reason to learn and speak another language. It has long been understood that "English is the only language relevant for the aspects of life that take place outside of home" (Source C). And people should not be blamed for this, since looking at how the world has developed in the last century, English has made its way to many corners of life due to its dominance established by politics and popular culture, especially with rise of the Internet where people automatically use English for conversations. Knowing English is an advantage that people want to gain because of its presence and dominance in today's world.

However, knowing only English is "a significant handicap" in a continuously-changing world (Source D). It is crucial to know that the English has not always been the dominant language, nor is the English language people know today the same with the English language of centuries ago. Empires rise and fall, along with the dominance of the language. If Spain and Portugal were able to conquer the world and split it in half in the 1400s people would not even think about a language such as English. To maintain the current status quo, a major English-speaking country like the United States has always been trying to understand the cultures of other countries in order to create benefits for its people. The benefits can come from establishing economic partnerships around the world, or maintaining a presence in a foreign country for influence. Either way, knowing the local languages is very important. Richard Hass, president of the Council on Foreign Relations, supported this idea by saying that people should learn "more Arabic for national security and more Mandarin, Hindi, and [...] Korean for the economy" (Source A). Ironically, if English speakers want to maintain the dominance of their language and love the easiness of speaking only one language everywhere, they have to... learn some other languages to achieve their goal. Thanks to the people who know more than just English, the United States is able to build a massive intelligence system around the world. What this means is that if people fail to know multiple languages in this ever-changing world, the probability of the dominance of their language and their country being lost approaches one.

Last but not least, there are many personal benefits that come with knowing more than one language, especially something besides English. Studies have shown that kids can "think better" when they know more than one language. And this is true. There are many ideas out there in the world than cannot be completely encapsulated by the English language. There is a reason why there are loan words such as "tsunami" and "karaoke." An English speaker knows karaoke as karaoke. A person who knows English and Japanese knows "kara" means "empty" and "oke" comes from "orchestra." That distinguishes them from the others in their ability to see and understand the world; it's a "'gateway' to a thorough understanding of other societies" (Source A). Knowing multiple languages creates opportunities for jobs in many developed countries around the world, not just in any English speaking country. A English speaker can move to Japan and live their happily if they know Japanese, because "try navigating Japan with only English." (Source F). Globalization is real, but it does not mean English has to be everywhere. But a person who knows more than just English is the one who can take every advantage this globalizing world has to offer to them. Just like foreigners learn English for more opportunities, the otherwise is also true.

Monolingual English speakers are at a disadvantage. It may not be clear for most people considering how the English is still a very dominant language in today's world, but slowly and surely they are giving away their opportunities to become better citizens of the 21st century. Immigrants come to countries like the United States looking for better life and they succeed, that can represent the result of multilingualism, the ability to adapt to different cultures and societies, and not really because they learn English to become successful.
