The document compares characteristics of poor and rich countries. It argues that the difference is not due to the age of the country, availability of natural resources, or intellectual ability. Rather, the key difference is the attitudes and principles followed by most people in each society. Rich countries generally have populations that embrace ethics, integrity, responsibility, respect for laws, work ethic, savings, initiative, and punctuality. In poor countries, only a minority tend to follow these principles in their daily lives. If more people in poor countries adopted these attitudes, it could help the country develop.
