The Exploitative Model: Analyzing Urban Economic Divides

Walk through almost any major city in the world and you’ll notice something striking: gleaming skyscrapers stand just a few kilometers away from crumbling neighborhoods with broken roads and no running water. This isn’t just a visual contrast – it reflects a deeply structural reality about how cities are organized economically. The exploitative model of urban growth offers a critical framework for understanding exactly this: why cities are divided the way they are, how wealth flows through urban spaces, and who ultimately pays the price for urban prosperity.

What is the exploitative model? 🔗

The exploitative model is a conflict-theory-based approach to understanding urban development. Unlike descriptive models that simply map how cities look, the exploitative model asks a harder question: who benefits from urban growth, and who bears its costs? It argues that cities are divided into distinct zones based on economic disparities and the ownership of resources, and that wealth systematically flows from poorer zones toward more affluent ones. The model was developed along the Detroit River and divides urban space into three semi-circular concentric zones based on a population’s ability to pay and access resources.

This stands in direct contrast to neutral or functional views of cities. As sociologists Feagin and Parker noted, political and economic leaders actively shape urban growth in ways that consistently benefit middle and upper classes while working against the interests of poorer residents. The exploitative model gives this observation a spatial structure – showing precisely where in the city these dynamics play out.

The three zones explained 🔗

The exploitative model divides urban space into three zones that reflect increasingly unequal levels of resource access, infrastructure quality, and economic power. Understanding each zone is essential to grasping how the model works in practice.

The city of death 🔗

The innermost zone is called the city of death – and the name is deliberate. This zone is defined by extreme deprivation: crumbling infrastructure, absence of basic services, high mortality rates, and daily survival challenges. Residents here are largely invisible to mainstream urban policy and economic life. According to UN-Habitat, urban inequality is starkly expressed through differential access to income, healthcare, sanitation, and education – and those gaps are sharpest at the very bottom of the urban hierarchy. Globally, over 30% of urban populations in developing regions live in informal settlements, marked by inadequate housing and a lack of basic services like clean water and secure land tenure. The city of death captures these conditions in their most severe form.

The city of need 🔗

The middle zone is the city of need. Residents here have access to some basic services but continue to face significant economic hardship. This zone often sits between the city of death and the affluent outer zone, functioning as a labor reservoir for the broader urban economy. People in this zone work in factories, service industries, and informal markets – their labor supports the city’s wealthier areas – but they rarely see the economic returns of that contribution flow back to their own neighborhoods. Research from the Federal Reserve Bank of Minneapolis confirms that neighborhoods trapped in poverty tend to stay that way, even as the broader city grows wealthier – a pattern entirely consistent with what the exploitative model predicts.

The city of superfluity 🔗

The outermost zone is the city of superfluity – the area of concentrated wealth, resources, and decision-making power. Here, residents enjoy high-quality infrastructure, well-funded schools, accessible healthcare, and proximity to economic opportunity. Studies tracking U.S. neighborhood data from 1970 to 2010 found that affluent neighborhoods show high rates of persistent stability – their wealth is self-reinforcing over time. From 1973 to 2003, the income of households in the top five percent grew by 75%, while median household income rose by only 13%. The city of superfluity is also where political and planning decisions are made – often without meaningful input from residents of the other two zones.

How wealth flows from poor to rich zones 🔗

One of the most important and counterintuitive insights of the exploitative model is the direction of wealth transfer. Popular narratives often suggest that wealth in prosperous neighborhoods eventually “trickles down” to poorer ones. The exploitative model challenges this directly. In reality, the labor, land, and economic activity of the poorer zones generate value that is captured disproportionately by the wealthier zone.

Research from the Urban Institute found that high wealth and income in larger urban areas do not translate to better conditions in their lowest-income neighborhoods – in fact, those at the bottom are often worse off in the largest cities than in smaller ones. Urban scholars have also noted that globalized financial economies and speculative land markets have driven low-income populations to the urban periphery while “homogenizing” central city areas for affluent classes. The city of superfluity, in this sense, expands at the direct expense of the other zones.

This is also visible in how land is used and rezoned. As sociological research documents, political and economic decision-makers routinely rezone public land in poor neighborhoods for industrial use, while protecting and upgrading land in wealthier areas. Exchange value – the market price – is consistently prioritized over use value – what the land actually means to the people who live and work there.

Social implications: what this means for real people 🔗

The zones of the exploitative model are not just economic categories. They shape health outcomes, educational access, and life expectancy. The World Health Organization has documented that people living in informal settlements are systematically excluded from decent employment, security, and the capacity to improve their own health outcomes. The WHO’s Commission on Social Determinants of Health raised a pointed question: why do we keep treating people for illness only to return them to the very conditions that made them sick?

In the cities of death and need, these conditions compound one another. In sub-Saharan Africa, urban informal settlements have seen a proliferation of low-fee private schools precisely because government educational investment is absent – meaning the poorest families must pay for what wealthier areas receive for free. Residential segregation, as documented extensively in urban sociology, is linked to inadequate education, poor health, and lack of employment – reinforcing what the exploitative model describes as a cycle of resource deprivation in the lower zones.

Meanwhile, research from the Max Planck Institute found that urban inequality is not simply an accident or side effect – it may actually scale predictably with city size. As cities grow and become more productive, elite wealth concentrations grow with them. This suggests the exploitative dynamic is not a temporary feature of cities that will resolve itself with development, but a structural pattern embedded in how urban economies work.

Real-world examples of the exploitative model 🔗

The exploitative model’s three zones are visible across very different urban contexts, though they manifest differently depending on local history, policy, and economics.

In post-industrial cities – like Detroit, Rustbelt cities in the United States, or former manufacturing hubs in the UK – neighborhoods that once thrived on industrial employment have become cities of need or death as investment withdrew and jobs disappeared. The infrastructure was never replaced, and these areas became pockets of concentrated deprivation within otherwise functioning metropolitan areas.

In rapidly growing cities in the Global South, the dynamic is often reversed spatially but structurally identical. Cities like Mumbai, Lagos, or Dhaka see affluent districts expand outward or consolidate in central areas, while informal settlements – housing millions of workers whose labor supports the formal economy – receive minimal public investment. The World Bank has documented that in cities like Dhaka, unemployment rates for the poorest male workers are roughly double those of the wealthiest – a structural gap that keeps the city of need firmly in its place.

In large Western cities, the pattern often plays out through gentrification: the city of superfluity expands into what was the city of need, displacing existing residents rather than improving their conditions. Economic segregation research shows that gentrification can temporarily mix rich and poor households, but over the long term, segregation and inequality increase again in those same neighborhoods.

Addressing the divides: what does change look like? 🔗

Recognizing the exploitative model’s dynamics points toward what kinds of policy responses might actually work. Superficial interventions – like infrastructure upgrades in poor areas without also addressing land tenure, employment, and political representation – rarely break the underlying cycle.

Effective change requires, first, that residents of the city of death and city of need have a genuine voice in urban planning decisions. Community-led urban planning that involves local residents ensures policies address actual needs rather than external assumptions. Second, resource distribution through urban policy – including equitable school funding, public health investment, and affordable housing – must be deliberately targeted at closing the gaps between zones, not just improving the overall city average. Third, land use policies that protect communities from displacement and speculation can slow the extractive flow of value from poorer to wealthier zones.

UN-Habitat’s framework for urban development emphasizes multi-dimensional approaches to urban poverty – recognizing that economic, social, and spatial inequality must all be addressed together. Without this holistic lens, urban growth risks simply producing a bigger city with the same three zones, just at a larger scale.

What do you think? If the exploitative model is right that wealth flows systematically from poorer to richer urban zones, what would genuinely equitable urban planning need to look like – and who would need to be in the room to design it? And given that research suggests urban inequality may grow predictably with city size, is it possible for a large, thriving city to also be a genuinely fair one?
