Most of koreans has equilibrium oriented mind internally. Equilibrium oriented means the mind that  all the citizens have to share same portion of valuable resource. Many koreans thinks that they should not be imperior to others even though he cannot be superior to others. For example, if somebody buy a good quality of car or household goods, his neighborhood can be comfortable even after he acquire better quality of household goods. If soneone give a good quality of extra private education to his children, his neighbor is comfortable even after his children getting more expansive private eduacation. Korean’s highschool level equalization policy also tells how much koreans equilibrium oriented. I think that Koreans are really reluctant to give in the others in any competition. They cannot live with putting down in any competition.
