What is the main difference between high-income and developing countries?
Here is my take: People in the former have much more of pretty much everything. Almost everyone living in high-income countries has access to electricity; in poor (low-income) countries, 7 out of 10 people don’t. Most families in rich countries own a car, but only a few people living in the developing world do. On per capita basis, rich economies have 15 times more doctors than poor countries, consume 40 times more energy, have 50 times more ATMs, and so on.
