Today, i watched the video about Japanese population has been deceased. This topic is not only for Japan, but also Korea has same issue with population. Because of increasing of well-educated people, the people do not want to be lower-class labor such as buliding cleaning staff, waiter and part-time job at supermarket. It caused people avoid to work at those kind of job. Part-time job is not a lower-class job, also it is neccesery to keep our society goes on. The more people want to be upper-class. the more cost wii be needed. It will make our society hard to get married or have children. Every parents started to worry about their children’s future, especially their job. To prevent this situation, we need to change our thinking about job and common sense for our society.
