Maybe, It could be too many colleges, not too many students, which have diluted the value of a bachelor's degree. Pretty many colleges are being closed because they have not been able to find enough students to enter the colleges, especially in Korea. Except for how many clolleges there are, quality of their curriculum could be another reason. They are usually easy to enter and get the bachelor's degree, but students cannot get enough knowledges or skill from them. It is just same as wasting time and money for students.
