There is a fear that runs through African and Caribbean economic policy. It is not named. It is rarely discussed. But it explains why the textile mills closed, why the cotton is still exported raw, why the gold remains in foreign vaults, and why the African Union cannot break from the extractive systems that have strangled the continent for generations. It is the fear of the interstice.
The interstice is the gap left behind when a system withdraws, collapses or is destroyed. Not a void. Not a vacuum waiting to be filled. The West calls it a vacuum. They panic. They rush to fill it with loans, aid, trade agreements, and military bases. Their logic demands that every space be occupied, measured, controlled, by them. African metaphysics has always understood the interstice differently. The Kongo call it the hollow, the printing chamber where realities are imprinted before they emerge. The Akan know the threshold between the living and the ancestors. The Yoruba map the Odu, the space where opposing forces balance. Ubuntu accepts the distance between persons as part of relation. The Mandari name the margin that cannot be utilized.
The interstice is not empty. It is the condition for new creation, for sovereignty, for independence, for liberation.
Yet the architects of African and Caribbean development policy have been terrified of it. Arthur Lewis, the Nobel Prize-winning economist from St. Lucia, built his entire model on avoiding the interstice. His critics, the Plantation School of Lloyd Best, Norman Girvan, and George Beckford, understood that the interstice was necessary, but they could not convince the policymakers. And today, the same fear paralyses the African Union and most heads of state. They negotiate for better terms within the existing system. They do not demand a new system nor prepare for an alternative. Because they are afraid of what happens if the old system withdraws and they are excluded from what comes.
This blog post traces that fear from Lewis to the present, using the textile industry as the thread that runs through the entire story. Because cotton was the colonial crop. And the cloth tells the truth.
ARTHUR LEWIS AND THE REFUSAL OF THE INTERSTICE
Arthur Lewis was born in St. Lucia in 1915. He was the first Black professor at the London School of Economics, the first Black person to hold a full professorship at the University of Manchester, and the first Black winner of the Nobel Prize in Economics. He was a staunch anti-imperialist who had personally taken on the English economic establishment over the West Indies' "right to industrialise" and won. He advised Kwame Nkrumah. He shaped the economic policy of newly independent nations across Africa and the Caribbean.
Yet his model of development was designed to avoid the interstice at all costs.
Lewis's Dual Sector Model, published in his 1954 paper "Economic Development with Unlimited Supplies of Labour," divides the economy into two sectors: a low-productivity subsistence sector (traditional agriculture, crafts, the informal economy) and a high-productivity capitalist sector (modern industry). The model predicts that surplus labour from the subsistence sector will move to the capitalist sector, attracted by higher wages. Industrialization will proceed. Wages will eventually rise. The economy will transform.
Crucially, Lewis saw the subsistence sector as having "unlimited supplies of labour." The marginal productivity of additional workers is zero or even negative. Removing them from farming does not reduce output. This surplus labour can be drawn into the capitalist sector without raising wages, because the subsistence sector provides a constant supply of workers desperate for any wage above survival.
The model assumes that labour will move voluntarily. Workers see higher wages in the factory. They leave the farm. They are replaced by others. The process continues until the surplus labour is exhausted. At that point, wages rise across both sectors, and the economy becomes fully developed.
Lewis did not consider all factors. He assumed that labour would move from one sector to the other without any gap. The subsistence sector would shrink. The capitalist sector would expand. There would be no space between, no pause, no uncertainty. The transfer would be smooth, continuous, and automatic.
The textile industry was central to this vision. Lewis advised Kwame Nkrumah's government in the Gold Coast (now Ghana) in 1953, recommending that the state should "pioneer" industries and then sell them once they became viable. Cotton was the obvious starting point. It was the major cash crop. It could be spun, woven, and printed locally. Foreign capital would be invited in to build the mills. Local labour would leave the farms and enter the factories.
But Lewis did not ask what would happen if the foreign capital refused the invitation. He did not ask what would happen if the mills closed. He did not anticipate that foreign capital might prefer to extract raw materials at low cost, ship them elsewhere for processing, and capture the value-added profits in their own countries. Why would he, living during the heights of the struggle of liberation, not see how the colonisers structured the realities of the economies we lived in?
PART TWO: WHAT LEWIS OVERLOOKED
The first problem with Lewis's model is that labour does not move voluntarily when it is forced. Colonial taxation policies in German East Africa (now Tanzania) deliberately created a cash shortage. Local people could not pay their taxes. To raise cash, men left textile-producing areas to seek wage work on distant plantations. The textile industry in Ufipa began to decline in the first decade of the twentieth century, not because of competition from imported cloth, but because colonial taxation policies destabilized the local labour supply.
Lewis assumed that the subsistence sector was simply less productive. The evidence shows that colonial taxation made it impossible for people to remain in the textile industry sector. They were not attracted to higher wages. They were fleeing the tax collector.
The second problem is that Lewis assumed that once labour moved to the capitalist sector, the process would be self-sustaining. The evidence from Nigeria tells a different story. Nigeria had approximately 200 textile mills in the 1970s and 1980s, employing 600,000 workers. The mills were built with foreign machinery, foreign management, and foreign capital. Then the Structural Adjustment Programme (SAP) was imposed in 1986. The government withdrew support, assuming farmers could produce cotton as a business without guidance. The farmers were smallholders, mostly illiterate. They could not sustain production without extension officers. Land degradation followed. Soil samples were sent to India; investors refused to invest because the land was degraded. Imported cotton seeds failed to germinate. Locally developed seeds from research institutes existed, but importers bypassed them for personal profit. The mills collapsed. Today, fewer than 20 remain.
The third problem is that Lewis assumed the labour transfer would be permanent. The evidence shows that when the mills closed, workers did not return to productive subsistence farming. They migrated to cities for informal work, or they remained unemployed. The capitalist sector did not expand. The subsistence sector did not recover. The interstice opened, but it was not a space prepared for local industry. It was a wound.
The fourth problem is that Lewis assumed that the capitalist sector would eventually absorb all surplus labour. The evidence from across Africa shows that labour has moved from agriculture directly to services, bypassing manufacturing entirely. This happened largely because trade liberalization exposed manufacturing to global competition that African industries could not withstand. Today, 90 percent of Africa's production exports are unprocessed goods. The structural transformation that Lewis predicted did not happen.
The fifth problem is that Lewis assumed that wages are determined solely by labour supply and demand. The evidence from Ethiopia and Kenya shows that national labour laws and enforcement matter more. Kenyan apparel workers earn approximately three times more than their Ethiopian counterparts, not because labour is scarcer in Kenya, but because Kenya has sector-specific statutory minimum wages and stronger enforcement. Ethiopia has no statutory private-sector minimum wage, weak enforcement capacity, and limited worker representation. Foreign-owned factories in both countries tend to pay lower wages than domestic firms. This contradicts the Lewis assumption that foreign capital automatically benefits local workers.
The sixth problem is that Lewis assumed that the international economic order was neutral. The evidence from Lesotho shows that the country's entire textile sector is dependent on US trade policy. When the US threatened a 50 percent tariff in April 2025, Lesotho's government declared a two-year state of disaster. Over 20,000 jobs were at risk. Factories announced temporary closures. The sector employs approximately 30,000 to 40,000 workers. The Lewis model assumes that once labour is absorbed into manufacturing, the process is self-sustaining. Lesotho's textile sector is dependent on US buyer orders. When those orders disappear, the jobs disappear. This is not a turning point. It is a single point of failure.
THE PLANTATION SCHOOL AND THE DEMAND FOR THE INTERSTICE
The Caribbean critics of Lewis, the Plantation School of Lloyd Best, Norman Girvan, and George Beckford, saw what Lewis refused to see. They called his strategy "Industrialization by Invitation" as a deliberate dismissal. Best famously accused Lewis of being "epistemologically an Englishman," arguing that his intellectual framework was so shaped by British classical economics that he could not conceive of a development path that did not pass through foreign capital.
The Plantation School argued that the Caribbean economy was not a "dual economy" waiting to be developed. It was a single, integrated plantation economy, a socio-economic unit that remained structurally unchanged from slavery through independence. Its purpose was not local development. It was raw extraction for external powers. The capitalist sector was not the solution. It was the problem.
For the Plantation School, the interstice was not something to be avoided. It was something to be created. They called for industrialization by intention, state-led diversification away from monoculture, land reform to break up the plantation estates, and regional economic integration to create scale. They understood that the withdrawal of foreign capital would create a gap. That gap was necessary. It was the space where local industry could grow.
Girvan articulated the central difference: "In the Lewis model, foreign capital in industry is part of the solution while in the Plantation model it is part of the problem." The Plantation School looked backward at the structural limitations of the economy, the history of extraction, monoculture, and external control. Lewis looked forward to a strategy of industrialization without fundamentally altering those structures.
George Beckford authored the classic Persistent Poverty: Underdevelopment in Plantation Economies of the Third World (1972). He argued that plantation economies are "high-cost export propelled satellites specializing in producing raw materials for export." The Caribbean economy was not waiting to be developed. It was actively being held back by the very structure that Lewis wanted to work within.
But the Plantation School could not overcome the fear. The policymakers listened to Lewis. They invited the foreign capital. The textile mills were built. And when the mills collapsed, the Plantation School's warnings were vindicated, but it was too late. The interstice had opened as a wound, not as a workshop.
COTTON AS COLONIAL CROP
Cotton was not a neutral material. It was not just another crop. It was the fibre that financed the transatlantic slave trade. It was the raw material that powered the Industrial Revolution in England. It was the commodity that colonizers extracted from Africa, shipped to Europe, processed into cloth, and sold back to Africans at a profit.
The focus on cotton in African textile production was not natural. It was engineered. Before Europeans arrived, Portuguese-speaking Africa used raffia, palm fiber, sisal, wild rhubarb root dyes, and other local materials. Cotton became dominant because it was exportable. Colonial regimes controlled it, channeled it into global trade, and extracted it for profit rather than local use. The knowledge of how to work with raffia, palm fiber, and sisal was not written. It was not patented. It was not passed down. And because those materials had no export value, their knowledge systems were not valued.
The Kuba people of Central Africa are renowned for a specific process that turns stiff raffia plant fiber into a soft textile. Men weave the base cloth from fine raffia fibers. Women then create intricate geometric patterns using a specialized cut-pile embroidery technique. After the pile is cut, the fibers are rubbed together, which gives the surface a silky lustre reminiscent of velvet, hence the name "velvet raffia." This was historically used as a form of currency, as ceremonial dress, and to adorn royal stools. An unprocessed raffia fiber is stiff, but after these specialized techniques, it can be as soft as cotton, with a luxurious velvet-like feel. This is not just a craft. It is a sophisticated material engineering process.
But the colonial economy had no use for raffia. It could not be exported in bulk. It could not be processed in European factories. It could not be taxed at the same rate. So raffia was ignored. Its knowledge system was not protected. And today, the knowledge to make velvet raffia is at risk of being lost.
The cotton textile industry in Africa was not designed to develop the continent. It was designed to manage the labour surplus. Lewis's model, with its "unlimited supplies of labour" moving voluntarily from subsistence to industry, provided an economic justification for this structure. He assumed labour would move because wages were higher. He did not account for the fact that labour had to be forced, taxed, or coerced into wage employment. He did not account for the soil degradation that followed monocropping. He did not account for the fact that when the mills closed, the workers could not simply return to farms that had been depleted and abandoned.
The cotton was colonial. The mills were colonial. The collapse was colonial. The interstice that opened was not a space for African industry. It was a space for Asian imports and European second-hand clothing. And the leaders were afraid to demand anything different, because they feared the interstice.
THE AFRICAN AND CARIBBEAN CRITICS OF LEWIS
African and Caribbean intellectuals have been critiquing Lewis for decades.
Lloyd Best (Trinidadian) was the most important critic. He coined the term "Industrialisation by Invitation" specifically to ridicule Lewis's model. He argued that Lewis's strategy, attracting foreign capital to build industry in the Caribbean, would lead to foreign control, dependency, and lack of genuine transformation. Best's most devastating line: he called Lewis "epistemologically an Englishman," meaning that even though Lewis was Black and from the Caribbean, his intellectual framework was entirely shaped by British classical economics. He argued that Lewis "was brought up by Ricardian and Smithian theories and he was Stanley Jevons professor in the University of Manchester. He had to be an Englishman."
Norman Girvan (Jamaican) was a member of the New World Group of Caribbean economists that directly challenged Lewis. In his 2008 lecture at the University of the West Indies, Girvan articulated the central difference: "In the Lewis model, foreign capital in industry is part of the solution while in the Plantation model it is part of the problem." He documented that the attacks on Lewis were personal. Many of his generation saw Lewis "with his English accent and bearing similar to that of an English academic" as "the epitome of the black Englishman." Girvan also noted that Lewis was hurt by these attacks, admitting as much to a colleague.
George Beckford (Jamaican) authored Persistent Poverty: Underdevelopment in Plantation Economies of the Third World (1972). He led the "Plantation School" which argued that Caribbean economies are "high-cost export propelled satellites specializing in producing raw materials for export." The plantation school's ultimate critique of Lewis was precisely that he overlooked the structural limitations of the economy.
Walter Rodney (Guyanese) wrote How Europe Underdeveloped Africa (1972). While not directly mentioned in the search results, his work is a full-throated critique of the kind of development thinking that Lewis represented. Rodney argued that Africa's underdevelopment was not a lack of integration into the global economy, but the specific form of that integration, extractive, coercive, and designed to benefit Europe.
Kwame Nkrumah (Ghanaian) directly disagreed with Lewis over the Volta River Project and the Akosombo Dam. Nkrumah is "often portrayed as a politician who ignored economic experts." But the evidence shows that Nkrumah "was also trained in economics and wrote several books on political economy examining why and how African energy resources had been exploited and underdeveloped during the colonial era." Nkrumah advocated "energy developmentalism," the achievement of progress by maximising the energy under state control at all costs. Lewis advised against it, favouring a more cautious, market-oriented approach. Nkrumah believed that controlling energy infrastructure was the prerequisite for industrialization. Lewis believed that industrialization would create its own demand for energy.
These critics confirm that you are not alone in questioning Lewis's assumptions. The reason Lewis did not account for external control of Africa's resources is not that he was unaware of it. It is that his policy advice was aimed at working within the existing international economic order, not overthrowing it. He took the existing economy as a starting point, and instead of questioning it, he recorded and analyzed the problems. The plantation school, by contrast, argued that the status quo itself was the problem.
HOW EUROPE USED LEWIS AGAINST AFRICA AND THE CARIBBEAN
The evidence shows that European powers, specifically Britain, actively used and promoted the Lewis model as a deliberate strategy to manage their post-colonial relationship with Africa and the Caribbean.
The British Colonial Office adopted "industrialization by invitation" as a deliberate strategy. British officials framed it as the "rational" and "apolitical" path to development. They rejected proposals for a Caribbean development bank or regional development corporation that would have given local leaders planning power. The model served British interests by attracting foreign capital while limiting British financial risk and maintaining influence.
France operated through direct state control rather than private investment. France "continued to provide Africa with industrial goods under near monopolistic conditions and to restrict local manufactures to foodstuffs, beverages, and household items." French West Africa was required to pay its own way as a colony. The administration imposed forced labour (courvee) and imprisonment (indigenat) to extract resources and maintain control. They fostered production of groundnuts and cotton "where appropriate conditions were present and imposed taxation as a means of inducing participation in the cash economy." No African middle class emerged. The French system was harsher, more centralized, and left no room for African accumulation.
Portugal controlled its African territories for over 400 years. Portuguese colonialism was notoriously extractive and repressive, lasting until the mid-1970s, well after Lewis published his model. The Portuguese did not develop industry in their colonies. They extracted raw materials, including cotton, using forced labor systems that were only abolished late in the colonial period.
Belgium's Congo was a textbook case of extraction without transformation. Under King Leopold II and later the Belgian state, the Congo's rubber, copper, cobalt, and diamonds were extracted using forced labor, mutilation, and terror. No industrial base was built. No capitalist sector emerged.
The Netherlands, through companies like Vlisco, created a different but related structure. Dutch wax prints have been sold to West African markets since 1846, predating Lewis by over a century. The Dutch did not industrialize Africa. They industrialized a product for Africa, produced in Europe, and sold back. African consumers shaped the demand. African labour never entered the "capitalist sector" of production.
What Lewis did was provide an economic model that made this structure appear natural and efficient. By assuming an "unlimited supply of labour" that would move voluntarily if wages were higher, he allowed European powers to claim they were following market principles while ignoring the violence, coercion, and political control that actually maintained the system.
THE SAHEL EXCEPTION
Burkina Faso, Mali, and Niger, three landlocked Sahelian nations formerly colonized by France, are in the process of taking direct control of their natural resources, particularly gold, uranium, and other minerals. Under the leadership of the Alliance of Sahel States (AES), these countries have broken from traditional Franc-afrique arrangements where French companies controlled mining concessions, tax regimes, and currency reserves.
The key shift: resource revenues are increasingly being directed toward domestic infrastructure, factories, and industrial development rather than being extracted and repatriated to France.
Mali has asserted control over its gold mining sector, renegotiating contracts and increasing state ownership in mining operations. The government has redirected mining revenues toward infrastructure projects, including road construction and energy generation. Burkina Faso has increased state control over mining concessions and is channeling resource revenues into industrial development, including textile and manufacturing sectors. Niger, one of the world's largest uranium producers, has moved to reduce French control over its uranium mines and reorient resource revenues toward domestic development priorities.
These nations have severed military ties with France. They have expelled French diplomats. They are building infrastructure with their own resources. They are not waiting for permission.
And they are being punished. Suspended from ECOWAS. Threatened with sanctions. Accused of moving toward "authoritarianism." The interstice is being weaponised against them. The message to other African leaders is clear: if you try to leave, you will be isolated.
The Sahel nations are proving that the interstice is survivable. They are not collapsing. They are not being reinvaded. They are not starving. They are building roads, refineries, and factories with their own gold. The interstice is not an abyss. It is a workshop.
THE FEAR OF THE INTERSTICE TODAY
The fear of the interstice paralyses the African Union and most heads of state. They see the Sahel nations punished. They draw back. They stay within the lines. They negotiate for scraps.
The vacuum is not the absence of Western systems. The vacuum is the absence of African systems to replace them.
The interstice is not a void. It is a printing chamber. It is the hollow where new realities are imprinted before they emerge. It is the threshold between worlds. It is the balance of opposing forces.
The Kongo understood this. They called the hollow (oco) the most primitive form that emerged from the bottom of the first matter, dark matter (ndobe/piu), which is the "printing chamber" of all realities. The source states: "The hollow (oco) is the most primitive form that emerged from the bottom of the first matter, 'dark matter' [ndobe/piu], which is the 'printing chamber' of all realities… A 'printing chamber' for realities that were and realities to come."
The Akan understand the space between wiase (the corporeal world) and asamando (the land of the ancestors). These two worlds are not strictly separated. The source states that the spiritual world of the ancestors is "in no sense another world, but rather a part of this world." The space between them is a permeable threshold that souls cross during birth and death. This is the interstice that cannot be filled because it is the condition for the migration of souls.
The Yoruba understand the Odu, the 256 signs of the Ifá system that map the balancing of polarities, expansion and contraction, light and darkness. The source states: "Most systems of metaphysics are based on the belief that the primal polarity that sustains the physical universe is the tension between expansion and contraction. In Ifa this polarity is usually described as the relationship between darkness and light. This relationship is not considered a conflict between the forces of 'good' and the forces of 'evil.'"
Ubuntu understands the distance between persons as part of relation. The source makes a critical clarification: "The African aphorism incorporates both relation and distance." The space between persons cannot be eliminated. It must be accepted.
The West calls it a vacuum. They panic. They rush to fill it. They cannot tolerate the interstice because their logic demands that every space be occupied, measured, controlled by them. African metaphysics has always understood that the interstice is the condition for creation, recreation, liberation.
THE INTERSTICE IS NOT A PUNISHMENT
The West will not fill the interstice for us. They cannot. Their logic does not know how. The interstice is the one thing they cannot objectify, cannot control, cannot extract.
The Sahel nations are proving that the fear is a lie. They are not collapsing. They are not being reinvaded. They are not starving. They are building roads, refineries, and factories with their own gold. The interstice is not an abyss. It is the printing chamber.
Ghana is processing its own cocoa. Zimbabwe is processing its own lithium. The textile mills collapsed because the interstice was not prepared. They collapsed because the leaders were afraid to step into the gap and build while the gap was open. They invited foreign capital to fill it instead. And when the foreign capital left, the mills closed, the workers were dismissed, and the cotton continued to leave raw.
The interstice is not a punishment. It is an opportunity. It is the space where African systems can grow. But only if we are brave enough to step into it.
The fear of the interstice is the fear of our own capacity. It is the fear that we cannot build what we need. It is the fear that the gap will swallow us. The Sahel nations prove otherwise. Ghana and Zimbabwe prove otherwise. The textile mills collapsed not because the interstice was impossible, but because the leaders refused to enter it.
We can survive the interstice. Let's be brave enough to step into it.
