Personally, I see public education as a socializing institution, and believe that knowledge itself is already being privatized and mechanized. At school, we don't really master subjects like Korean, English, or Math, but rather learn how to get along in a community, communicate, and follow rules. That's one reason why private education is so developed, and in the same context, test takers and Korean middle and high school students turn to learning methods and resources outside the public school system to achieve better results in entrance exams.
