Young people take longer to grow up today than they did in the past, especially in the United States. The delay of transfer from adolescence to the adulthood has become a phenomenon in today’s society, and it has a new name called ” emerging adulthood.” Since more and more young people have a hard time to transfer from children to a real adult. Many sociologists and psychologists have debated that “whether the emerging adulthood should become a new stage of the lie.” Parents are also concerned about this phenomenon. However, despite the repeated criticism and the concerned, young people remain unchanged. Ethan Watters has written the article”Being WEIRD: How Culture Shapes the Mind.” In Watters’ article, he believes that human’s behavior and the cognition is shaped by the different culture. If the scientists want to examine how different individual will develop, they must pay attention to the culture. In “What Is it about 20-Somethings?” Robin Marantz Henig explained the different stage of life and introduced a new life stage ” emerging adulthood.” In the article, Henig mainly focused on the delay in today’s young people’s transfer from adolescence to the adulthood. Henig believes that the phenomenon of “emerging adulthood” could be found in all families in today’s western society. The emerging adulthood is unique in the United States; it could be back up in many different factors. The technology revolution creates more job opportunities that required high education. Therefore young people have to spend more time on study. The delay in finding a job and settle down will directly cause the delay of marriage. Young people in western countries are more likely to see themselves as an individual, therefore the age of 20 to 30 become a period for young people to explore their possible life direction. Firstly, the technology revolution creates more jobs opportunities that required high education. ” Among the cultural changes he points to that have led to “emerging adulthood” are the need for more education to survive in an information-based economy; fewer entry-label jobs even after all that schooling;”(200 Henig). American in the past 30 years, relatively few people attend college or have an education beyond high school, or even just finished high school. There are also few people didn’t go that far, they step into the society without getting high education. In the present, most of the American teenagers go to college, and many of them even go beyond the university. The technology revolution is the “pushing hand” that pushes young people to go back to school and get a higher degree. The technology revolution is not just the smartphone and the Wifi that people uses every day. The technology revolution is the transition of a country from manufacturing economy to an industrialized and knowledge economy. In the present, people getting used to making things with the machine that maybe no longer need people to make it by hand. In the United States, a lot of manufacturing jobs have gone to other countries because of the cheaper labor. However, the use of machine instead of labor creates more emerging industries that need high-tech talents to support it. All of those jobs require education beyond high school. Go back to school and get a higher degree is the only way that you can have a chance to get the best new jobs in the knowledge economy. “Americans, without fully realizing it, were manifesting a psychological tendency shared with people in other industrialized countries that had been refined and handed down through thousands of generations in ever more complex market economies”(496 Watters). When people are constantly live in an individualized society, they will form a unique development that other countries can not imitate or copy. Under the great situation of the technology revolution, more people get more education for a longer time than ever before, and it pushes everything out because most of the young people can not get a job several years after they graduate. This phenomenon of emerging adulthood is unique in the United States because of the unique culture, and the unique revolution has shaped different development.Secondly, Young people in western countries are more likely to see themselves as an individual, therefore the age of 20 to 30 become a period for young people to explore their possible life direction. ” The “weird” Western mind is the most self-aggrandizing and egotistical on the planet: we are more likely to promote ourselves as individuals versus advancing as a group”(498 Watters). “emerging adulthood: identity exploration, instability, self-focus, feeling in-between, and a rather poetic characteristic he calls “a sense of possibilities”(200 Henig). In the western mind, people are individual after they are 18. However, the different system and law treated young people immature. ” People can vote at 18, but in some states, they don’t age out of foster care until 21″(201 Henig). The society declares that 18 means adult, however, on the other hand, do not give young people a chance to be responsible.Finally, most American 20-somethings prefer to wait for marriage and parenthood until after they settle down.
