For a long time, the American workforce has been becoming increasingly specialized, which means that an increasing amount of education and preparation is required for many careers. A high school diploma was once a guarantee of a person's ability to handle most job skills, but this is no longer the case. In many instances, a person with only a high school diploma faces difficulties finding well-paying positions with job security. A few years of college, and preferably a degree, are now almost necessary qualifications. 长时间以来，美国劳动力日趋专业化，这就意味着大量岗位越来越需要有教育背景的职工。高中学历曾一度是个人工作能力的保证书，但现在却不再起效。很多例子说明，一个高中文化的人在找高薪，有保障的工作时会困难重重。几年的大学教育和高程度的学历已成为目前必要的就业资格。 The Facts 事实 As the cost of a college education goes up, many begin to question whether the expense is worth the reward. Simply examining the financial differential between those with a college degree and those without one reveals that the more educated a person is, the more, on average, he will earn in his lifetime. It is estimated that people with a college degree earn almost twice as much as those with only a high school diploma; even those with only a few years of college or an associate's degree earn close to a quarter more. Though the burden of tuition and loans can seem heavy, the cost of remaining uneducated is obvious. |
