With the development of the society, more and more people enroll in the postgraduate examination for getting a high diploma. It is believed that high diploma equals to high ability and profound knopanies are inclined to hire the people mercial life. Furthermore, Sam Walton of Wal---Mart Stores Inc. does not a MBA degree, but they are the most successful man in mercial.
In my opinion, diploma does not equal to knoe from your hard work and endowment. If you got a diploma by dishonest behavior, no matter how high a diploma it is, it were just a piece of paper, and you were as blank as that paper.
