Thinking about a part-time job

Yesterday, I wrote a part-time job. I want to work, too. I don’t deny that there are some problems to a part-time job. But when people become 20, they must prepare economic independence. Compared with foreign countries, Koreans don’t stand up for themselves until a late age. Of course, students cannot earn much money with a part-time job. But if they money easily from their parents, how can they provide for their future social lives?
