Dual economy

The dual economy is a model of development that divides a country into a modern sector of urban life, industry, and advanced technology and a traditional sector of rural life, agriculture, and institutions regarded as less productive. The book argues that the distinction can describe real economic differences, but it cannot by itself explain their origins: in South Africa, the divide was made by policy, and the modern economy depended on the impoverishment and exclusion of the people assigned to the traditional one.

The model and its limits

In 1955, Sir Arthur Lewis proposed the dual economy paradigm, which continues to shape how social scientists understand the economic problems of less-developed countries. In this account, the modern sector is associated with cities, industry, and advanced technology; the traditional sector with rural life, agriculture, and institutions and technologies characterized as backward. Communal ownership of land is one example in the model, because it is taken to imply the absence of private property rights. Lewis argued that labor in the traditional sector was used so inefficiently that workers could move to the modern sector without reducing rural output. Development, in this framework, meant shifting people and resources from countryside and agriculture into cities and industry. Lewis received the Nobel Prize in 1979 for his work on economic development.

The book accepts that the model identifies a real division in some economies, while rejecting the inference that the division is necessarily a natural stage of development. If the traditional sector is poor because of its institutions and low productivity, development might appear to require its gradual transformation into a modern one. But that explanation misses how the two sectors can be connected: policy may actively produce poverty in one sector so that the other can draw on its land and labor. The division then does not merely mark different levels of development; it organizes who benefits from economic activity and who is kept from its gains.

South Africa's constructed divide

South Africa offers a stark example of the apparent contrast. The former Natal and the Transkei, divided by the Great Kei River, were described as different economic worlds. On the Natal side, private property, functioning legal systems, markets, commercial agriculture, and industry accompanied relative prosperity. Across the river, the Transkei had communal landholding and powerful traditional chiefs until recently; its population faced poverty and limited access to modern conveniences. Read through Lewis’s model, the contrast might appear to show a traditional sector waiting to become modern.

The book reverses that interpretation. The dual economy between Natal and the Transkei was recent and politically created, not a timeless reflection of Africa’s natural backwardness. White elites shaped the poor rural sector to provide a reserve of cheap labor for white businesses and to reduce competition from Black Africans. As the book notes, the South African and Botswanan regions avoided many adverse effects of the slave trade and its associated wars. The Dutch East India Company established a base at Table Bay in 1652, in a western region then sparsely settled by Khoikhoi hunter-gatherers; farther east, agricultural societies, including the Xhosa in what are now the Ciskei and Transkei, initially had limited contact with the colony and were far enough inland to attract little attention from slave traders. That earlier history does not make the later divide natural: the book locates its formation in subsequent political and economic arrangements.

The decisive legal instrument was the Natives Land Act of 1913. It allocated 87 percent of South Africa’s land to Europeans, who made up about 20 percent of the population, and 13 percent to Africans. Earlier measures had already confined Africans to shrinking reserves, but the 1913 act institutionalized the division and designated reserves including the Transkei and Ciskei as African Homelands. These territories later became known as Bantustans under the Apartheid regime’s claims about African origins and entitlement to land. The formal division of territory thus helped establish a system in which the white minority held political and economic rights while the Black majority was excluded from both.

The act also restricted how Black sharecroppers and squatters could farm on white-owned land: their future arrangements were to be service contracts, rather than partnerships in land or its produce. Africans could sometimes receive permission to cultivate a defined plot as part of their compensation, but the rules barred them from paying the landholder for the right to occupy the land. The measure narrowed independent access to land and made wage labor in the white economy more necessary.

Labor, education, and unequal development

The contrast between Homelands and the prosperous white economy could look to development economists in the 1950s and 1960s like confirmation of Lewis’s account: one sector urban and educated, the other rural, poor, and technologically backward. Yet the Homelands’ conditions were not simply inherited. Government policy had evicted Africans from land, crowded them into territories too small to provide an independent livelihood, and pressed them to seek work in the white economy. As economic incentives collapsed, advances made in the preceding decades were reversed: people abandoned plows and returned to hoes, if they farmed at all. Many were instead made available as cheap labor.

Labor restrictions reinforced the land regime. A racial occupational barrier first imposed in mining was extended across the economy in 1926 and remained in force until the 1980s. The state also restricted the education that might have allowed Black Africans to enter skilled work. The Bantu Education Act, passed in the 1950s under Hendrik Verwoerd, embodied a policy that confined African education to service within their own communities and denied them a place in the broader European-controlled economy beyond designated forms of labor.

This was not the gradual transfer of unskilled workers into more productive jobs envisaged by Lewis’s model. The modern sector’s success relied on keeping the traditional sector in place: white employers profited from low wages for Black workers, while restrictions prevented those workers from competing for skilled occupations and better-paid work. The Homelands were therefore not simply a problem awaiting the spread of growth; their poverty and isolation helped sustain the white economy.

The resulting development was sharply unequal and ultimately limited. White South Africans had property rights, invested in education, and could profit from gold and diamond exports. More than 80 percent of the population, however, was marginalized and excluded from most desirable economic activities. Black South Africans were denied the opportunity to develop their abilities as skilled workers, businesspeople, entrepreneurs, engineers, or scientists. The book presents this as an extractive arrangement: the wealth of one group was built in part on the constrained opportunities and labor of another.

Ending the divide

The political structure upheld the economic one. Before its overthrow in 1994, South Africa vested political power in whites, who alone could vote and hold office, and who dominated the police, military, and political institutions. At the Union’s establishment in 1910, the Afrikaner polities of the Orange Free State and the Transvaal explicitly barred Black political participation. Natal and the Cape Colony allowed Black men to vote subject to property qualifications that most could not meet; by the 1930s, Black people had been explicitly disenfranchised throughout the country.

The dual economy ended in 1994, but not through the automatic progression from traditional to modern development that Lewis’s theory might suggest. Black South Africans protested a regime that denied their basic rights and withheld the gains of economic growth. After the Soweto uprising of 1976, protest became more organized and stronger, ultimately bringing down the Apartheid state. The book therefore links the end of the divide to political mobilization and the empowerment of Black South Africans, just as it links the divide’s creation to the political force of white South Africans.

Wider significance

The argument also situates South Africa’s experience within a broader history of uneven development. European commercial and colonial expansion helped fuel growth in parts of Europe while imposing or reinforcing extractive institutions elsewhere. The expansion of Atlantic trade, for instance, created opportunities for wealthier English traders to challenge royal control; elsewhere, European power could suppress independent commerce and strengthen extraction. The book emphasizes that the same broad expansion could have sharply different institutional consequences depending on who controlled trade and political power.

The dual economy consequently serves both as a description and as a caution against mistaking description for explanation. A visible gap between an affluent modern sector and a poor traditional one does not show that the latter is simply a remnant of an earlier stage, nor that development will naturally erase it. In South Africa, law and political power shaped the divide, restricted land and education, and made the poorer sector useful to the richer one. Understanding the pattern requires asking how the two sectors were made to relate, and whose interests their relationship served.
