Arthur Lewis

Arthur Lewis was an economist whose account of the dual economy became a powerful framework for thinking about development. First proposed in 1955, it divided less-developed economies into a modern sector of cities, industry, and advanced technology and a traditional sector of rural agriculture and less productive institutions. The book credits Lewis with identifying a real economic divide, while arguing that South Africa exposes the danger of treating such a divide as a natural condition destined to disappear through growth: there, political power deliberately produced and preserved it.

The Dual-Economy Framework

Lewis’s model described two sectors within a less-developed economy. The modern sector was associated with urban life, industry, and advanced technologies; the traditional sector with rural life, agriculture, and institutions and technologies characterized as backward. Communal landholding, in this account, meant an absence of private property rights in land. Lewis also argued that agricultural labor was used so inefficiently that workers could move into the modern sector without reducing the rural sector’s output.

This account made the movement of people and resources from countryside and agriculture toward cities and industry central to the development problem. Economists who built on Lewis’s work treated that movement as a route from a traditional economy to a modern one. Lewis received the Nobel Prize in 1979 for his work on economic development, and the framework continued to shape how social scientists understood less-developed economies.

South Africa as a Divided Economy

The book calls South Africa one of the clearest examples of a dual economy, and uses the border between Natal and the Transkei to make the contrast concrete. The Great Kei River marks a boundary between a coastal and interior landscape of private property, commercial agriculture, industry, and functioning legal systems, and a region historically characterized by communal land, powerful traditional chiefs, and poverty. Lewis’s framework can describe the visible contrast; the book’s argument is that it cannot by itself explain how that contrast came to exist.

For development economists visiting South Africa in the 1950s and 1960s, the prosperous, urban, educated white economy and the poor, rural, technologically less developed Homelands appeared to fit Lewis’s model. But these conditions were not simply remnants of a timeless past. They had been made through government policy and European colonialism. The South African state took land from Africans and crowded many into Homelands too small to support independent livelihoods, leaving them dependent on work in the white-controlled economy. As incentives to invest in farming collapsed, people abandoned plows and returned to hoes, or ceased farming altogether.

An Economy Made by Policy

The state also restricted the occupations and education available to black South Africans. A racial colour bar, first imposed in the mining sector and later extended across the economy, lasted until the 1980s. The government withheld investment in black schools and discouraged black education; in the 1950s, under Hendrik Verwoerd, it enacted the Bantu Education Act. These policies did not simply leave workers behind as industry advanced. They helped keep black workers unskilled and barred them from skilled occupations, protecting white workers from competition and preserving higher wages for them.

That arrangement inverted the developmental sequence implied by a natural transition from traditional to modern work. In South Africa, the modern sector depended on the continued existence of the poor one: Homelands supplied workers whose limited economic options helped white employers pay low wages. The book therefore distinguishes Lewis’s analytical category from the political order built in South Africa. Both involve a modern and a traditional sector, but only the latter was deliberately structured to keep one population’s labor cheap and its opportunities restricted.

Limits and Historical Significance

The white economy did achieve substantial prosperity. White South Africans had property rights, invested in education, and profited from gold and diamond exports. But more than 80 percent of the population was excluded from most desirable economic activities and could not readily become skilled workers, businesspeople, entrepreneurs, engineers, or scientists. The book presents this inequality not as a temporary imbalance on the way to inclusive development, but as the result of extractive institutions that made white wealth depend on black exclusion. That dependence also limited the kind of economic development the system could sustain.

The dual economy ended in South Africa in 1994, but not through the gradual economic transformation Lewis’s framework might lead one to expect. Black South Africans organized and protested against a regime that denied basic rights and withheld the gains of growth. After the Soweto uprising of 1976, resistance became stronger and more organized, ultimately bringing down the apartheid state. The book’s reassessment thus preserves Lewis’s contribution—the recognition that economies can contain starkly different sectors—while showing why the origins and persistence of those sectors must be explained through political power, institutional choices, and the distribution of economic opportunity.
