[originaltext] At high school, students may begin to question the importance

At high school, students may begin to question the importance of a college education. The answer is that attending college provides graduates with opportunities that are not as widespread to those with a high school diploma.
   For many high school students, being able to immediately get an income after graduation is an appealing idea. They may also be discouraged from attending university by the rising cost of tuition rather than by poor academic performance. While a higher education may be one of the largest expenses you will ever face, its importance has become quite clear in terms of earning potential within today’s economy.
   The most important word to describe a college education is opportunity. As opposed to generations of the past, high school graduates today are unable to obtain the high-paying jobs that were once available. The United States has become a knowledge-based economy. A college education serves as the gateway to better options and opportunity.
   There are additional reasons. At college, students have the opportunity to read books and listen to the lectures of top experts in their fields. This encourages students to think, ask questions, and explore new ideas, which provides college graduates with an edge in the job market over those who have not experienced a higher education.
   The importance of a college education is also linked to the opportunity to gain valuable resources. The more connections you collect at college, the more options you will have when you begin your job search. Once you have started your career, a college degree often means greater promotion opportunity.
