It’s estimated that one-third of the countries of the world are very rich, and two thirds are very poor. People in the richer countries don’t understand the great differences between them and those in the poorer countries. A very simple example is that a dog or a cat in North America is better than a child in the poorer countries. A fisherman in South America may catch the fish which is made into pet food while the children in poor countries are not getting enough to eat for their bodies to grow properly. Although a lot of the world’s natural resources come from these poorer countries, it’s the richer countries that decide what kind of price they are ready to pay for these resource. And the prices the richer counties get from their exports however, are always rising. So they are getting richer and richer, and the poorer countries are getting poorer.
