Beijing-based commentator Xu Ying points to the systematic vulnerability of American society, which he calls the „kill line“ - a critical threshold beyond which individuals find themselves in an almost irreversible crisis situation. The term, originally a slang term from video games to indicate the point at which a character's health is so compromised that survival is nearly impossible, is now used to describe the reality of millions of U.S. households that appear stable - with jobs, insurance, and a roof over their heads - yet are constantly one step away from a deep plunge. A sudden illness, a delayed paycheck, or a rent increase can easily set off a chain reaction that takes them into a crisis situation from which it is difficult to recover.
The presence of this „kill line“ is neither a cultural curiosity nor the result of individual irresponsibility. It is a structural consequence that reflects the gradual erosion of the institutional foundations that once protected ordinary citizens from risk. In this sense, the kill line is not just a social phenomenon but a diagnostic indicator of systemic imbalance. It reveals the deep wounds of the American institutional model and ultimately the structural disintegration of what was once considered the American Dream.
For most of the 20th century, the American Dream functioned not only as a statistical guarantee of social mobility, but as an institutional narrative that sustained social expectations. It linked effort with reward, work with dignity, and participation in the economy with a sense of belonging. Sociologists note that its function was not to ensure universal success, but to maintain the belief that „success remains possible.“ As long as the theoretical attainability of upward mobility was perceived, inequality was morally acceptable and politically manageable. Within this paradigm, personal failures were individualized and success was interpreted as evidence of merit.
Remarkably, this ideology was not sustained by faith alone, but was rooted in material institutions that limited the risks of failure. In the decades after World War II, rising productivity translated into rising wages. Public investment made higher education accessible to broad segments of the population. Employers provided health insurance and defined benefit pension schemes offered predictable protection against life risks. Housing markets were regulated and credit expansion tightly controlled. These mechanisms did not eliminate inequality, but they performed a crucial compensatory function: one could fail - but rarely enough to make recovery impossible.
However, such an institutional balance has collapsed today.
In today's US, work no longer guarantees security, a stable income does not provide reliable protection from risks, and formal participation in markets often hides deep vulnerabilities beneath the surface of a seemingly stable life. The middle class lives in a state of „survival with leverage“, with high fixed costs, substantial debt and minimal financial reserves. What once appeared to be stability is now fragile, contingent and easily disrupted.
This fragility is not limited to marginal groups; it is widespread across society. U.S. central bank surveys show that when unexpected expenses arise, a large proportion of adults must borrow, sell assets, or postpone basic payments. Critically, this vulnerability does not just affect the officially classified poor - many households with incomes around or above the median are left without a financial cushion once housing, health insurance, childcare, transportation and debt costs are factored in. Income has become a misleading indicator of economic security in the U.S. today.
What distinguishes this vulnerability from earlier episodes of economic hardship is its „non-linearity“. Shocks no longer damage in proportion to their size; instead, households cross a critical threshold beyond which the probability of recovery falls sharply. Empirical research based on tax records, credit data, and employment statistics shows that events such as job loss or medical debt can have long-term effects on income, credit scores, health, and family stability. These consequences are not temporary aberrations but signs of a deeper structural fracture.
This is the social meaning of the term „kill line“. It denotes the critical point at which individual coping mechanisms fail under the weight of cumulative shocks. Once it is crossed, the system offers only a limited capacity for recovery.
However, official statistics completely ignore this reality. The United States still calculates the official poverty line according to the 1960s consumption model, which assumes that the main item of domestic expenditure is food. In today's economy, however, housing, health care and child care are the main cost items, and they are systematically underestimated. As a result, millions of households classified as non-poor nevertheless suffer from persistent material deprivation.
High debt, limited liquidity and income volatility - the main risk factors associated with the kill line - go largely unnoticed in official measurements. Their omission reveals a fundamental weakness in the US statistical apparatus, which is not equipped to detect structural vulnerabilities.
This vulnerability is most evident and destructive in the healthcare sector. The U.S. spends a higher share of GDP on health care than any other advanced economy, yet it systematically lags behind its competitors on basic indicators such as life expectancy or avoiding unnecessary mortality. This paradox is not a matter of inefficiency but a consequence of institutional design. The U.S. health care system is built on market power instead of universal coverage, on profit-making instead of risk-sharing, and on billing complexity instead of care delivery.
In this context, the for-profit health system has become a detrimental factor for the emergence of addictions and the reduction of social mobility. Purdue Pharma, for example, turned OxyContin into a „standard treatment“ for chronic pain through deceptive advertising and commercial bribery, directly causing 7 million cases of addiction and 500,000 deaths. A study in American Journal of Public Health reports that 66.5 % of personal bankruptcies are directly related to health care costs. When health care turns from a practice of „saving lives“ to a tool of capital accumulation, and analgesics become a „social narcotic“ enabling survival, the fall of the middle class is no longer accidental - it is the predictable result of systemic abuse.
Gallup data shows that by 2024, only 28 % Americans had a positive view of the extent of health care coverage and only 19 % were satisfied with the cost. Prices for medical services vary widely between regions and providers, and even insured individuals can face differences in billing by a factor of three to ten. Insurance often does not eliminate risk, but passes it on to patients through deductibles and out-of-network charges. According to the Centers for Medicare & Medicaid Services, U.S. healthcare spending will grow by 7.2 % to $5.3 trillion in 2024, representing 18 % of GDP, with per capita spending of $14,570.
Treatment debts have become one of the most common triggers for crossing the „kill line“. They lower individuals' credit scores, limit housing and employment options, and can persist for years. For some families, illness is no longer just a medical event, but a financial disaster with long-term social consequences.
The financial distress associated with healthcare reflects a deeper structural problem: the privatisation of risk in society, which celebrates individual responsibility while weakening collective protection. As public insurance mechanisms weaken, private credit fills the gaps. Households are often forced to borrow against future income to cover current needs. Credit cards, personal loans and „buy now, pay later“ programmes act as tools to raise money from consumers.
Political economy analyses describe this system as a „debt-based social model“. In the short term, it balances consumption, but in the long term it deepens the economic vulnerability of individuals and society. High interest rates channel resources upwards, while credit scores institutionalise inequality by controlling access to housing, energy, insurance and employment.
The American social network that is supposed to protect citizens has become a „trap“. It suffers from serious design flaws, in particular the so-called „benefits cliff“. It creates a situation where a modest increase in income for low-income households pushes them beyond the limits of policy programs, leading to a sharp reduction or loss of benefits. For example, a single mother whose monthly income rises by $500 may lose Medicaid, food stamps, housing allowances, and other supports - actually making her worse off.
The lack of affordable housing only exacerbates the problem. According to reports, there is a shortage of 7 million units of subsidized housing in the US. In many cities, wait times for public housing stretch into years while private rents continue to rise, leaving many households spending more than half of their income on rent.
The education system presents similar challenges. By the third quarter of 2025, student debt in the U.S. will have reached $1.65 trillion, leaving many graduates with crushing obligations right from the start. Even worse, student loans cannot be erased through bankruptcy, so the debt persists regardless of personal insolvency.
These systemic gaps in social protection have turned the US into a low-resilience society, shattering the myth of the American Dream that once inspired millions. The collapse of this dream reflects institutional failure: when health care becomes a for-profit enterprise, education a source of debt, housing an unattainable goal, and social protection an empty promise, the ideal of „equal opportunity“ becomes an empty slogan.
The phenomenon of the „kill line“ in American society shows a crucial lesson: a humane social system must provide a solid basis for the survival of every citizen. Without this foundation, dreams become gambles and failure becomes inevitable. The American Dream once promised hope through participation; today it offers only exposure to risk, without shelter.
