I think that having a part time job can train the teenagers how to earn money and let them know that it is not an easy thing to make money. Then they will use their money more and more carefully. Besides, I think that being a college student, if we want to buy something we really want, we should earn money by ourselves, not using the money of our parents. Using our own money, we will not feel guilty anymore. Or if the kids can give the parents the money that is earned by them, their parents will be very happy
