In a primary school in South Korea, a teacher asked the students to think how happy they are when watching a video of children with famine in Africa. The teacher meant that they must be happier compared to poor children. Then one of the students responded "It's wrong that one feels happy to know other's unhappiness." When I read this article, I deeply agreed with the student. I think most of the NGOs for children in need are using that kind of way to move people and to encourge them to donate. That is, the organizations make people compare themselves to the poor and feel happier and sympathy for the poor. Then they would be willing to donate for the poor. I think this method is effective but wrong. I wonder if those organizations take the wrong method or I am wrong. Could you please let me know your opinion on this issue?
