1. The difference between poor and rich countries is not due to their age, natural resources, or the intelligence of their people. 2. Rich countries like Japan, Switzerland, Canada, Australia, and New Zealand became wealthy because most of their people embraced principles like ethics, integrity, responsibility, respect for laws and others, work ethic, savings, and punctuality. 3. In poor countries, only a minority follow these basic principles that are essential for development. If more people in poor countries adopted these principles through education and culture, they could change their situation and become developed.
