The Tale of Two Nogaleses: A Microcosm of Inequality

Key Insight

The city of Nogales, divided by a border fence, starkly illustrates global inequality. On the Arizona side, average household income is about $30,000 annually. Residents typically achieve high school graduation, have high life expectancy, and access services like Medicare, electricity, modern sanitation, and a robust road network. They live with law and order, can invest without fear of expropriation, and experience a stable democracy where they vote to elect and replace their representatives.

Just a few feet south, in Nogales, Sonora, average household income is roughly one-third of their northern neighbors'. Many adults lack high school degrees, and numerous teenagers are not in school. The population faces high infant mortality, poor public health, and a shorter life expectancy. Public amenities are deficient, with bad roads, high crime, and significant challenges for businesses due to complex permissions and corruption. Democracy is a recent development, with the region under the control of the corrupt Institutional Revolutionary Party (PRI) until political reforms in 2000.

These profound differences are not due to geography, climate, disease environment, or the ethnic backgrounds of the inhabitants, who share ancestors, food, and culture. The fundamental distinction lies in the economic and political institutions on each side of the border. These institutions create vastly different incentives for individuals, entrepreneurs, and businesses, acting as the primary driver behind the disparate levels of economic prosperity observed between the two Nogaleses and their respective nations.
