“The more you learn, the more you earn,” said the pop singer Cyndi Lauper as she accepted her high school diploma(证书) , at the age of 35 ! Although Cyndi made it without a high school degree, most people don't. In the USA today, about 75% of jobs need some education or technical training further than high school. The lowest wage earners in the USA are those without high school degrees; college graduates(毕业生) outearn those without a college education. People with master's degrees(硕士学位)outearn those with only a bachelor (学士学位); and the highest incomes of all are earned by people with advanced professional or academic degrees. These generalizations explain why most of young Americans go to college. However, despite the averages, more diplomas don't always mean more money. Many skilled blue-collar workers, salespeople, business executives, and entrepreneurs(企业家)outearn college professors and scientific researchers. And great athletes and entertainers outearn everyone else!
