Why Nations Fail: The Origins of Power, Prosperity, and Poverty

on the contrary, the governments provide services, including education, health care, roads, and law and order. Notable, too, is the fact that the citizens vote in elections and have some voice in the political direction their countries take.
    The great differences in world inequality are evident to everyone, even to those in poor countries, though many lack access to television or the Internet. It is the perception and reality of these differences that drive people to cross the Rio Grande or the Mediterranean Sea illegally to have the chance to experience rich-country living standards and opportunities. This inequality doesn’t just have consequences for the lives of individual people in poor countries; it also causes grievances and resentment, with huge political consequences in the United States and elsewhere. Understanding why these differences exist and what causes them is our focus in this book. Developing such an understanding is not just an end in itself, but also a first step toward generating better ideas about how to improve the lives of billions who still live in poverty.
    The disparities on the two sides of the fence in Nogales are just the tip of the iceberg. As in the rest of northern Mexico, which benefits from trade with the United States, even if not all of it is legal, the residents of Nogales are more prosperous than other Mexicans, whose average annual household income is around $5,000. This greater relative prosperity of Nogales, Sonora, comes from maquiladora manufacturing plants centered in industrial parks, the first of which was started by Richard Campbell, Jr., a California basket manufacturer. The first tenant was Coin-Art, a musical instrument company owned by Richard Bosse, owner of the Artley flute and saxophone company in Nogales, Arizona. Coin-Art was followed by Memorex (computer wiring); Avent (hospital clothing); Grant (sunglasses); Chamberlain (a manufacturer of garage door openers for Sears); and Samsonite (suitcases). Significantly, all are U.S.-based businesses and businessmen, using U.S. capital and know-how. The greater prosperity of Nogales, Sonora, relative to the rest of Mexico, therefore, comes from outside.
    The differences between the United States and Mexico are in turn small compared with those across the entire globe. The average citizen of the United States is seven times as prosperous as the average Mexican and more than ten times as the resident of Peru or Central America. She is about twenty times as prosperous as the average inhabitant of sub-Saharan Africa, and almost forty times as those living in the poorest African countries such as Mali, Ethiopia, and Sierra Leone. And it’s not just the United States. There is a small but growing group of rich countries—mostly in Europe and North America, joined by Australia, Japan, New Zealand, Singapore, South Korea, and Taiwan—whose citizens enjoy very different lives from those of the inhabitants of the rest of the globe.
    The reason that Nogales, Arizona, is much richer than Nogales, Sonora, is simple; it is because of the very different institutions on the two sides of the border, which create very different incentives for the inhabitants of Nogales, Arizona, versus Nogales, Sonora. The United States is also far richer today than either Mexico or Peru because of the way its institutions, both economic and political, shape the incentives of businesses, individuals, and politicians. Each society functions with a set of economic and political rules created and enforced by the state and the citizens collectively. Economic institutions shape economic incentives: the incentives to become educated, to save and invest, to innovate and adopt new technologies, and so on. It is the political process that determines what economic institutions people live under, and it is the political institutions that determine how this process works. For example, it is the political institutions of a nation that determine the ability of citizens to control politicians and influence how they behave. This in turn determines whether politicians are agents of the citizens, albeit imperfect, or are able to abuse the power entrusted to them, or that they have usurped, to amass their own fortunes and to pursue their own agendas, ones detrimental to those of the citizens. Political institutions include but are not limited to written constitutions and to whether the society is a democracy. They include the power and capacity of the state to
