Firstly, citizens of both wealthy nations and poorer nations are human beings. Therefore, we can not look at, hear of, or talk about people who lack food, education, etc without compassion and sympathy. Sharing wealth with poorer nations is not only a good deed but is also a task. Many nations in Africa and Asia are very very poor. Diseases, crime and illiteracy are killing the citizens of these countries. If richer countries not help poor countries then poor countries will become more and more poorer while rich countries will become more and more richer. So, sharing wealth is an useful way to prevent people from that bad future.
