A "Rich People's Disease": Migrant Workers and Structural Disability in China - Xisai Song Notes

The ethnographic study conducted by Xisai Song, published in Medical Anthropology (2023), provides a deep investigation into the intersection of chronic kidney disease (CKD), rural-to-urban migration, and the socio-economic structures and health disparities in contemporary China. The research centers on the concept of "structural disability," exploring why Chinese rural migrant workers often perceive biomedical chronic care as a "rich people's disease" ($fu\,gui\,bing$) and why they frequently evade or discontinue standardized medical treatments in favor of alternative healing pathways.

The Clinical Trajectory and Social Reality of Jinwei

The article opens with the illustrative case of Jinwei, a construction worker in his mid-30s. After a 25-hour train journey and an additional hour by bus, Jinwei returned to his rural village in southwest China for the lunar new year. He had been experiencing swollen feet and extreme fatigue while working on a construction site in a coastal province. Although previously diagnosed with hypertension at a street clinic—a diagnosis he neglected to follow up on due to work demands—Jinwei visited a county hospital during the spring festival of 2018, where he was diagnosed with chronic kidney disease (CKD). A nephrologist at a tertiary hospital in the provincial capital later confirmed the diagnosis.

Upon visiting a hemodialysis ward, Jinwei was physically and emotionally overwhelmed by the sight of patients on treatment beds with blood circulating through tubes. This visual encounter, combined with the doctor's warning to start a treatment plan to prevent kidney failure, induced a state of panic. Jinwei’s life as a migrant worker, which spanned 15 years and four different provinces, was fundamentally incompatible with a biomedical treatment model that demands residential stability, long-term medication, and a lifestyle void of heavy physical labor. To attempt compliance, he moved to Chengdu, the provincial capital, took a lower-paying job in a furniture factory, and visited a renowned tertiary hospital monthly. However, the anxiety of monitoring biological indicators and the financial strain of the "rich people's disease" led him to a confrontation with his doctor and the eventually abandonment of the biomedical regimen. He eventually returned to high-risk construction work out of financial desperation, fainted on the job, and was diagnosed with end-stage kidney failure.

Research Methodology and Demographic Landscapes in Qiushui County

Xisai Song’s research is based on 12 months of ethnographic fieldwork conducted between 2018 and 2019 in Qiushui, a mountainous and underdeveloped county in southwest China. The primary site was a county public hospital's hemodialysis ward. The ward consisted of 95 patients, $68$ of whom were young or middle-aged former migrant workers. The age distribution included $10$ patients in their 20s, $18$ in their 30s, $21$ in their 40s, $15$ in their 50s, and $4$ above the age of $60$.

The therapeutic histories of these workers revealed significant patterns: more than half ($37$ patients) were diagnosed only after reaching end-stage kidney failure. Among the remaining $31$ who were diagnosed earlier, only $3$ adhered to a biomedical plan. The rest either invested life savings into controversial experimental cures ($6$ patients) or combined biomedicine with Traditional Chinese Medicine (TCM). The fieldwork involved participant observation, home visits, and interviews with patients, village doctors, county clinicians, and elite nephrologists in major cities like Beijing, Shanghai, and Chengdu.

The Theoretical Framework of Structural Disability

Song introduces the term "structural disability" to describe how socio-economic and geopolitical inequalities shape the experience of chronicity and disability. Unlike studies focusing on the elderly in the Global North (e.g., Kaufman 2015), these migrant workers are young and experience CKD as an immediate life crisis. Structural disability challenges the dichotomy between chronic and acute conditions, suggesting that for those in precarious labor positions, a chronic condition is experienced as a structurally produced acute crisis.

This concept draws from disability studies and black feminist anthropology. It posits that disability is a relational category created by social and material conditions that "dis-able" participation in society (Ginsburg and Rapp 2013). While global health scholars like Paul Farmer (2004) emphasize medical access as a solution to structural violence, Song argues that biomedical encounters can actually reproduce social exclusion if they do not account for the inability of marginalized patients to maintain their economic and social lives while undergoing treatment.

Political Etiologies and the Global Burden of CKD

Approximately $9\%$ of the global population is estimated to have CKD, with the disease disproportionately affecting people of lower socio-economic status. In the United States, the incidence of kidney failure among African American communities is $3$ times higher than among White populations ($USRDS\,2019$). Anthropologists have identified "political etiologies" (Hamdy 2008) to explain how factors like heat, dehydration, and labor exploitation in places like central California (Horton 2016) predispose workers to kidney failure.

In China, the absence of epidemiological data on migrant workers and CKD is itself a form of social exclusion. Epidemiological knowledge typically relies on data from formal medical institutions and insurance schemes, which assumes consistent treatment-seeking behavior. Because many migrant workers do not visit formal institutions until they are in crisis, their disease trajectories remain largely invisible to national databases.

The Labor Landscape and Precarious Life of the Nong Min Gong

The category of "rural migrant workers" ($nong\,min\,gong$) refers to the internal migrants who moved toward urban coastal provinces following China’s 1978 economic reforms. In places like Qiushui, migration is the primary means of survival and a rite of passage for youth. However, these workers remain socially and politically excluded in cities, often living in segregated urban villages and lacking welfare entitlements.

Most migrant workers are informally employed; a 2017 report indicated that only $35.1\%$ of rural migrant workers had signed contracts with employers in 2016. Their labor landscape links compensation directly to physical strength. For these workers, chronic diseases are treated with painkillers as a "quick fix" to sustain intense work routines. CKD is particularly devastating because the medical advice to avoid heavy labor directly threatens their only source of income, transforming the illness into a total social and economic disability.

Monitoring and the "Countdown Timer" of Creatinine Levels

Biomedical CKD management relies heavily on tracking biological indicators, specifically creatinine. Drawing on the work of Dumit (2012) and Jain (2013), Song describes how these abstract numbers become personalized and take on weighted meanings. For migrant workers, a rise in creatinine levels is not just a clinical marker but a "countdown timer" toward kidney failure, unemployment, and social death.

In Jinwei’s case, the frustration of seeing fluctuating indicators despite his relocation to Chengdu and his career shift to a furniture factory (where he earned only half of his previous construction salary) proved unbearable. He viewed the treatment as inefficacious because it did not offer a quick return to his full labor capacity. The biomedical model's inability to provide a cure makes it appear as a "rich person's disease"—one that only those with residential and financial stability can afford to manage.

The Putian System and the Search for a Miracle Cure

Many patients, desperate to avoid the life-limiting reality of dialysis, turn to the "Putian system"—a network of private hospitals in China known for offering unconventional and sometimes fraudulent treatments in "gray zones," such as stem cell therapy or fetal cell transplants. Bo, a former printing factory manager, spent $200,000\,yuan$ (approximately $30,000\,US\,dollars$) at Putian-style hospitals in Beijing seeking a miracle cure.

Interestingly, the cost of a kidney transplant in China is often less than $200,000\,yuan$, yet patients like Bo often reject transplants. This is because a transplant recipient must still avoid heavy physical labor and take lifelong medication, meaning a transplant does not restore a manual laborer’s economic viability. For Bo, the inability to work led to a sense of social death; after a failed attempt to run a boba milk tea shop and facing continued physical exhaustion, he committed suicide in 2019.

Traditional Chinese Medicine and "Nurturing" ($Bao\,Yang$) the Kidney

When biomedical cures fail, many workers return to their home villages to seek Traditional Chinese Medicine (TCM) from local healers. These rural doctors often occupy the bottom of the professional hierarchy, holding degrees in "Integrated TCM and Western Medicine" ($zhong\,xi\,yi\,jie\,he$). However, their authority is rooted in local social worlds and long-term interactions with the community.

Yunhai, who was diagnosed with CKD in 2008, used TCM to "nurture" ($bao\,yang$) his kidney. This process involved visiting local healers, participating in online patient support groups, and consuming expensive tonics. His wife purchased cordyceps sinensis for him at a cost of $50\,US\,dollars$ per gram—a price equivalent to gold—spending a total of $20,000\,yuan$ (about $3,000\,US\,dollars$). They also practiced food therapy, such as cooking pigeon soup. For Yunhai, these practices provided a sense of agency and reestablished a post-migration life. He successfully postponed the need for hemodialysis for eight years through this self-directed "nurturing" plan.

Conclusion: Rethinking Chronic Care and Social Security

The article concludes that failure to manage chronic diseases among the marginalized is not simply a matter of individual noncompliance or poor scientific literacy. Rather, social exclusion is built into the biomedical model of chronic care. While the middle class may be able to live a "capable" life with chronic illness, for those whose survival depends on physical labor, chronic illness is an existential threat.

Song calls for a shift in health policy. Programs focusing solely on health education and medical access are insufficient. In 2021, public hospitals delivered $84.2\%$ of medical services in China, but outpatient coverage remains limited, forcing many migrant workers to pay out-of-pocket. Song argues that effective chronic disease care necessitates the provision of equitable social security to mitigate the effects of structural disability and protect the livelihoods of the most vulnerable populations.

The article explores the theme of "structural disability" in relation to chronic kidney disease (CKD) among rural migrant workers in China. It argues that socio-economic inequalities and the precarious nature of their labor significantly influence how these workers experience and manage their health conditions. The notion of structural disability suggests that marginalized individuals face additional burdens in accessing care, which can lead to a life crisis rather than merely a chronic health condition.

Furthermore, the article criticizes the biomedical model of chronic care for failing to address the realities faced by these workers, who cannot comply with treatment requirements due to their socioeconomic circumstances. The author calls for a reconsideration of health policies to provide more equitable social security and better support for vulnerable populations, emphasizing that chronic disease management should not solely rely on medical access or education but also on addressing structural inequalities.
