Global Patterns of Inequality and Economic Development

Key Insight

Sustained economic growth originated in England during the late eighteenth century Industrial Revolution, characterized by technological breakthroughs. This growth subsequently spread to Western Europe, the United States, and 'settler colonies' like Canada, Australia, and New Zealand. Today's thirty richest countries include these nations, along with Japan, Singapore, and South Korea, forming part of a broader East Asian pattern of recent rapid growth, also encompassing Taiwan and China.

Conversely, the world's thirty poorest countries are predominantly found in sub-Saharan Africa, joined by nations such as Afghanistan, Haiti, and Nepal. These extreme global distributions have remained remarkably consistent over the last 50 to 150 years; for instance, countries with average per-capita incomes under $2000 annually include most of Africa, Afghanistan, Haiti, parts of Southeast Asia, and North Korea. The richest, with over $20000 annual per-capita income, are North America, Western Europe, Australasia, and Japan. Within the Americas, a persistent hierarchy exists from the United States and Canada at the top, down to Bolivia, Guatemala, and Paraguay at the bottom.

While persistent, these patterns are not immutable; most current world inequality emerged only after the late eighteenth century, and historical rankings often differed significantly before this period, as seen in the Americas 500 years ago. Examples like Argentina's decline after being one of the world's richest by 1920, or the Soviet Union's rapid growth from 1930 to 1970 followed by collapse, highlight that prosperity can reverse. These stark, persistent, yet historically dynamic disparities raise fundamental questions about the causes of wealth and poverty, but widely accepted social science hypotheses often fail to provide convincing explanations.
