sub-Saharan Africa is central to the book’s account of why prosperity is distributed so unevenly across the world. It is not treated as a region held back by an inherent cultural incapacity or by geography alone, but as a place where political fragmentation and extractive institutions repeatedly restricted people’s incentives and economic opportunities. The account traces these conditions through the slave trade, colonial rule, and postindependence governments, while also stressing that history did not unfold identically everywhere: Botswana’s different trajectory shows that institutional change could take another path.

Poverty and the global divide

The book opens by setting the large differences in incomes and living standards between rich and poor countries against a broader global map. It names sub-Saharan Africa among the regions where poverty is widespread and notes that more than half the population lives in poverty in some of the world’s poorest countries. Later comparisons describe the average resident of the United States as about twenty times as prosperous as the average inhabitant of sub-Saharan Africa, and nearly forty times as prosperous as residents of the poorest African countries, including Mali, Ethiopia, and Sierra Leone. The point is not simply the scale of the gap: the book argues that such disparities endure because the institutions shaping people’s economic and political choices differ sharply.

The distribution of poverty has a striking persistence. Almost all of the thirty poorest countries in the book’s contemporary comparison are in sub-Saharan Africa. Looking back fifty, one hundred, or one hundred and fifty years, the countries at the bottom change in some particulars, but the overall pattern remains remarkably consistent. That continuity directs attention away from short-lived explanations and toward the historical institutions that reproduce disadvantage across generations. The book treats poverty as an outcome of political and economic arrangements, rather than as evidence that a population lacks the capacity to respond to opportunity.

Political fragmentation and institutional constraints

The account describes sub-Saharan Africa as having, across much of its history, fewer centralized states than other regions, and those states that did form were often highly absolutist and short-lived. Some collapsed; others exercised power without building lasting, broadly authoritative institutions. The comparison extends beyond Africa to Afghanistan, Haiti, and Nepal: despite their different locations, the book argues that these countries share a history of difficulty imposing order across their territories and sustaining the stability required for economic progress.

The Democratic Republic of the Congo illustrates how limited central authority can persist alongside intense extraction. European rule deepened insecurity of human and property rights, and colonial institutions enriched a narrow ruling group at the expense of the majority. After independence in 1960, extractive economic arrangements continued under extractive political institutions. The state comprised many precolonial societies and had little control over much of the territory. Mobutu used public power to enrich himself and his associates, including through the 1973 Zairianization program, which expropriated foreign economic interests, but he governed a weakly centralized state and relied on foreign assistance to counter secessionist threats from Katanga and Kasai during the 1960s.

The book presents this combination—political power concentrated among a few, alongside weak authority over the whole territory—as a pattern shared with much of sub-Saharan Africa. In the contemporary Democratic Republic of the Congo, it argues, extractive institutions persist because elites have little incentive to secure property rights, provide basic public services, or foster economic progress. Their interests lie instead in extracting income and maintaining power. Rival groups competing to control those institutions have further weakened any tendency toward state centralization. The resulting poverty is attributed not to geography, culture, or citizens’ ignorance, but to institutions that suppress incentives and limit the state’s capacity to serve the population.

Slavery, trade, and colonial disruption

The book’s account of Africa’s institutional history distinguishes its experience of trade from that of parts of Europe. The expansion of Atlantic commerce created new opportunities, but its effects depended on existing political institutions. In Kongo, contact with Portuguese traders expanded after Diogo Cão’s visit in 1483. Kongo was then a relatively centralized polity by African standards: its capital, Mbanza, had around 60,000 inhabitants, comparable in size to Lisbon and larger than London in 1500. Its rulers encountered European innovations, but the book stresses that the Kongolese were not inherently resistant to technology. They adopted firearms and used them in response to the incentives of slave trading; they also adopted literacy, European styles of dress, and house designs.

The issue, the book argues, was not an incapacity to innovate but the economic and political incentives facing people. The king could expropriate or tax their output, while individuals also faced the threat of being captured and sold. Under these conditions, investing to raise long-term productivity was risky. For the king, exporting enslaved people could be more profitable than making agricultural productivity a priority. The contrast between the adoption of guns and the failure of agricultural innovations such as the plow at scale helps make the argument concrete: technologies were available, but people had little reason to invest in practices whose benefits could be taken from them.

The book also resists portraying African economies as uniformly stagnant before European colonialism. In the nineteenth century, West African producers expanded exports of palm oil and groundnuts, while communities across southern Africa supplied goods to the industrial and mining districts of the Rand. Such experiments in changing production were, in the book’s account, undone first by European colonialism and then by postindependence governments. After the slave trade mostly ended following 1807, European colonialism reversed nascent modernization in parts of western and southern Africa and restricted possibilities for indigenous institutional reform. In areas including the Congo, Madagascar, Namibia, and Tanzania, colonial rule brought plunder, large-scale disruption, and mass violence.

The consequences of Atlantic trade differed across the Atlantic world. In England, profits from the slave trade helped enrich groups that opposed absolutist royal power. In Africa, the slave trade helped strengthen absolutist institutions. The book presents this divergence as the product of interaction between external opportunities and pre-existing political structures, not as a fixed difference between peoples. European colonial expansion then further entrenched extraction, often leaving African colonies with more complex institutional legacies than they had faced before colonial rule.

Independence, persistence, and divergence

In the decades of decolonization, independence might have opened a path to political and economic reform. The book argues that in many African countries it instead gave unscrupulous leaders an opportunity to intensify the extraction practiced under colonial rule. The political arrangements left by colonial government produced insecure and inefficient property rights, strong absolutist tendencies, and states that nevertheless lacked authority across their territories. In this account, postcolonial poverty reflects institutional persistence and adaptation: the people who inherited power often retained arrangements that benefited a narrow elite rather than creating reliable incentives for investment and economic development.

The book presents Botswana as an exception to this pattern. In the nineteenth century, King Khama began changes intended to modernize the political and economic institutions of his people. These changes survived the colonial period in part because Khama and other chiefs challenged colonial authority effectively. When independence created a critical juncture, those inherited institutions could be built upon rather than simply displaced, contributing to Botswana’s later political and economic success. The contrast underscores the book’s broader insistence on contingency: the same broad pressures did not dictate the same outcome in every society.

More broadly, sub-Saharan Africa’s position in the book is shaped by its relationship to international commerce and colonial power as well as by domestic political arrangements. European expansion could redirect trade, strengthen local absolutism, or impose institutions that blocked indigenous economic activity. Yet external pressure did not operate in a vacuum; the consequences were mediated by local structures of authority and the incentives of those who controlled them. The region’s history therefore serves as a sustained example of how unequal participation in global commerce and weak constraints on political power can reinforce each other.

Historical argument and significance

The book’s argument about sub-Saharan Africa is not a claim that every country followed one course. It draws comparisons across places and periods to explain a recurring pattern: where authority was fragmented or concentrated in extractive elites, property and human rights were insecure, and both individual investment and broader economic transformation were obstructed. In the Democratic Republic of the Congo, that pattern persisted through colonial and postcolonial rule; in the wider region, slave trading and colonial expansion damaged or redirected local economic initiatives; in Botswana, particular historical choices helped preserve a different institutional foundation.

This framework also challenges explanations that attribute poverty to culture or assume that technologies alone bring prosperity. The Kongolese adoption of firearms, the expansion of African exports in the nineteenth century, and the disruption of those efforts by colonial and postindependence governments all point to the importance of who controls resources and how political power is organized. Sub-Saharan Africa is thus both a region in the book’s account of global inequality and a key case in its explanation of how institutions, external economic forces, and contingent political choices combine to shape long-run development.
