In the past, too much emphasis was placed on diplomas in higher education. Most people thought, first get the diploma, then we'll see. But if everyone has diplomas, when they get into the job market, they will need ability. Possessing a diploma, but no ability, has lost its value.
過去高等教育太重文憑，普遍的心態是，先念一個學位再說，但如果大家都有學位，進入社會就看有沒有能力，沒有能力的學位是會「貶值」的。
