The logic of staying poor - Lessons from my patients!

She was rushed into the emergency room—it had been one year and six months since her last scheduled checkup. Her blood sugar and blood pressure were already through the roof—what a single consultation and adjusted medication could have managed early had become an emergency. When I asked why she had not been showing up to medical appointments, she did not say she lacked knowledge. She knew exactly what she needed. She said, with pain and fear in her eyes, that she had chosen feeding her children over the costs of her medical care.

As a medical doctor, I know this is not a one-off event. It is a pattern for many—the same logic repeats itself, as patients delay care until the day we meet in the emergency room.

As I eventually learned, people are not making irrational decisions. They are making entirely rational ones. The illness would wait, they reason. Their children’s hunger will not.

What I was witnessing, though I did not yet have the vocabulary for it, was a poverty trap.

A poverty trap is a self-reinforcing cycle in which the conditions of poverty today actively make it harder to escape poverty tomorrow. It is not simply about low income—it is about the way limited resources, vulnerability to shocks, and absent safety nets combine to keep people stuck, even when they are trying hard not to be. The structure of the environment works against the effort.

The healthcare dynamic I observed illustrates this clearly. My patient delayed treatment because she could not afford the upfront cost. The illness worsened, requiring care that was more expensive and more disruptive. During recovery, she was unable to work. To cover the bills, her family sold a goat, emptied their savings, and borrowed at high interest. What began as a manageable health problem eroded the very assets that might have cushioned the next crisis. One shock is often enough to keep families locked in the trap.

Research shows that financial scarcity places a severe tax on cognitive capacity. A study by Mani et al. (2013) found that the mental burden of poverty can reduce effective cognitive performance by the equivalent of up to 13 IQ points—suggesting that poverty does not just limit resources, but also the mental bandwidth needed to make optimal decisions. The choices being made in poverty are not careless, but instead they can be decisions made under constraint.

To measure the scale of this, we rely on frameworks like the Foster-Greer-Thorbecke (FGT) measures. The headcount ratio tells us how many people fall below the poverty line, while the poverty gap index shows how far below that line they fall on average. The Multidimensional Poverty Index (MPI) extends this by capturing deprivations across health, education, and living standards. These are powerful tools. But sitting in a clinic in Otukpo, I understood their limitation viscerally: they capture a moment in time. They do not capture the momentum — the way one bad week or one hospital bill can set off a cascade that takes years to recover from.

Poverty traps are about dynamics, not snapshots. They are about how constraints compound over time. This is why incremental income support alone is often insufficient — if vulnerabilities remain, households fall back again and again, unable to get out of the trap.

That is what makes this a policy problem, not just a personal one, thus the necessity of the work of organizations such as the World Bank Group. Breaking them requires systems that absorb shocks before they cascade—accessible healthcare, social protection, and financial mechanisms that do not force people to choose between treatment and feeding their children.

My patient made her choice at a crossroads that no one should have to face. My hope is that continued work to reduce poverty includes policies that can move that crossroads to a point where the choice doesn’t let the trap continue.
