In many places, including Korea, there is a strong relationship between education and social class why？

 This is because most of the high value-added jobs require a high level of education. In modern capitalist society, the higher value-added jobs earn more income. Most of these jobs require specialized skills. Most of the high-income jobs we know of, such as professionals, programmers, and researchers, require a high level of professionalism and a high level of education. Therefore, the higher the education level, the higher the income.

 However, in recent years, parents' economic power has been affecting their children's educational level or professional expertise. Parents with economic power are actively investing in their children's education because they know that higher education or higher education can lead to higher-income jobs. The problem is that children in families who are not financially able to receive support have reduced movement between classes, and class inheritance is occurring.

 In particular, this trend is remarkable in Korea. In Korea, without natural resources, education was the only way to raise or maintain the class, and the generation of parents generously invested in it. One of the factors fueling this situation is the ranking of universities. In Korea, the universities that you can go to are determined according to your grades, so the companies you can get a job from are different depending on the university you graduate from. In fact, the earned income of university graduates in Seoul is higher than that of graduates from local universities. So, the higher the parent's income, the more private education they invest, and their children enter better universities and get better jobs. In fact, most of the parents' earned incomes of students attending the top 10 universities in Korea show high incomes.

 While education can affect social class, parents' income should not affect their children's level of education. This is because it solidifies the succession of the class and competes on an unfair starting line. In the country, the quality of public education should be improved to narrow the gap with private education. If there is no significant difference between the education received at school and the private education, investment in education will decrease. In addition, the ranking of universities must be eliminated. Currently, Korean universities have their own grades for each university, and the university they graduate from shows their academic achievement as a teenager. Since this encourages private education, it is necessary to eliminate the ranking of educational institutions by setting specialized fields for each university, not for a specific university to lead all fields.
