Why Some Things Can't Be Bought with Money: The Non-Outsourceability of Care

One adult child spends thirty thousand dollars a month hiring a professional caregiver, providing their parents with round-the-clock medical-grade care. Another adult child quits their job to personally look after their parents, exhausted daily but attentive to every need. In terms of outcomes, the former may actually deliver higher quality care — yet in most cultures, the latter is considered more "moral." Why is this? Why must certain forms of labor be performed "personally" to hold value? Why are some things "not supposed to" be purchased on the market? This article attempts to deconstruct this seemingly simple yet profoundly deep moral intuition from the interdisciplinary perspectives of economics, game theory, sociology, and philosophy.

I. The Moral Boundaries of Markets: Sandel's Commodification Critique

Harvard political philosopher Michael Sandel, in his book What Money Can't Buy, mounted a systematic critique of market expansion.^[1] He distinguished between two types of arguments against commodification: the fairness argument and the corruption argument.

The fairness argument holds that when basic necessities enter the market, the poor are excluded due to inability to pay. This is a matter of distributive justice. But Sandel is more concerned with the corruption argument: once certain goods enter the market, their essential meaning is altered or corrupted. For example, friendship, love, respect, and civic duty — once these are exchanged for money, they cease to be what they originally were.^[2]

Care is a quintessential example of such goods. When adult children personally care for their parents, the act simultaneously conveys messages of "love" and "responsibility." But when care is outsourced to the market, even if the material content of care (feeding, bathing, companionship) remains exactly the same, its symbolic meaning undergoes a fundamental transformation — it shifts from a "gift" to a "commodity," from a "relationship" to a "transaction."^[3]

This is not to say that market-based care lacks value, but rather that it possesses a different kind of value. Economists habitually assume the completeness and transitivity of preferences, but Sandel's insight is that the value of certain goods cannot be measured by the same yardstick, because they belong to fundamentally incommensurable categories.^[4]

II. Signaling Theory: Personal Caregiving as a "Signal of Love"

Signaling Theory in economics provides a precise framework for understanding this phenomenon. Michael Spence, in his pioneering paper, pointed out that when information asymmetry exists, the party holding private information can transmit credible signals through "costly actions."^[5]

In the context of caregiving, a child's "love" for their parents is private information — parents cannot directly observe their child's inner feelings. Children need to "prove" their love through some form of action. According to signaling theory, an effective signal must be costly, and this cost must correlate with the sender's "type" — that is, the cost for a child who truly loves their parents must be lower than the cost for one who does not love them but wishes to pretend.^[6]

"Personal caregiving" is precisely such a costly signal. It requires investing substantial time, energy, and opportunity costs (foregone work income, social life, personal development). For a child who truly loves their parents, these sacrifices are "willingly made," with relatively low marginal cost; but for a child who does not love their parents yet wishes to pretend, these sacrifices are "painful," with extremely high marginal cost.^[7]

By contrast, "paying for outsourced care" is a low-cost signal. Given sufficient financial resources, anyone can hire a caregiver — regardless of whether they truly love their parents. Therefore, this signal cannot effectively distinguish between "high-love types" and "low-love types."^[8]

III. Mathematical Model of Costly Signals

Let us construct a simplified signaling game model. Assume there are two types of children: high-love type (H) and low-love type (L), in proportions of λ and (1-λ) respectively. Children can choose between two actions: personal caregiving (C) or outsourced care (O).

The cost of personal caregiving is:

• High-love type: c_H (lower, because it is "willingly done")
• Low-love type: c_L (higher, because it is "painfully forced"), where c_L > c_H

The cost of outsourced care is m (monetary expenditure), identical for both types.

Parents update their beliefs about the child's type based on the observed action and provide corresponding "moral evaluations" (or inheritance allocation, emotional rewards, etc.). Assume:

• The payoff for being perceived as the high-love type is R
• The payoff for being perceived as the low-love type is 0

Separating equilibrium condition: For "personal caregiving" to serve as an effective separating signal (chosen only by the high-love type, while the low-love type chooses outsourcing), the following two conditions must be satisfied:

1. Incentive compatibility condition (high-love type): The utility from choosing personal caregiving must exceed the utility from choosing outsourcing:

R - c_H ≥ 0 - m

That is: R ≥ c_H - m

2. Incentive compatibility condition (low-love type): The utility from choosing outsourcing must exceed the utility from choosing personal caregiving (and being mistaken for the high-love type):

0 - m ≥ R - c_L

That is: c_L - m ≥ R

Combining both conditions, the necessary condition for a separating equilibrium to exist is:

c_H - m ≤ R ≤ c_L - m

This requires c_L > c_H, meaning the caregiving cost for the low-love type must be significantly higher than for the high-love type. This is the core insight of signaling theory: the effectiveness of a signal derives from the cost differential between different types.^[9]

When this condition is not met (for example, when advances in caregiving technology reduce the cost of personal caregiving for all types), the separating equilibrium becomes unstable and the signal loses its discriminating power. This explains why in some societies, the moral authority of "personal caregiving" is declining — because the cost structure has changed.^[10]

IV. Incomplete Contracts and Moral Hazard: The Governance Dilemma of Outsourced Care

Even if we accept that "outsourced care" is a reasonable choice in certain circumstances, it still faces serious incomplete contracts problems. Oliver Hart and John Moore's contract theory points out that when a transaction involves too many quality dimensions that are difficult to specify in advance, the contract will be incomplete.^[11]

The quality dimensions of care are extremely complex:

• Material dimension: feeding, bathing, repositioning, medication administration — these are relatively contractible
• Emotional dimension: patience, gentleness, respect, companionship — these are extremely difficult to contractify
• Adaptive dimension: judgment and response to emergencies — these are nearly impossible to specify in advance

When contracts cannot cover all important dimensions, moral hazard arises: caregivers may shirk or cut corners on dimensions not specified in the contract.^[12] For example, a caregiver may administer medication on time (monitorable) yet remain emotionally cold and distant (difficult to monitor).

This is precisely what economists call the principal-agent problem.^[13] Children (principals) want their parents to receive high-quality care, but the caregiver's (agent's) incentives may not be aligned. Since the core quality dimensions of care are hard to monitor, this problem is particularly severe.

Williamson's transaction cost economics provides another perspective: when transactions involve high degrees of asset specificity and uncertainty, "hierarchy" (organizational internalization) tends to be superior to "market."^[14] Care is precisely such a transaction: it involves a high degree of interpersonal relationship specificity (caregivers must understand the care recipient's habits, preferences, and medical history) and is fraught with uncertainty (health conditions can change at any moment).

From this perspective, "personal caregiving" can be understood as a governance structure choice — choosing "family hierarchy" over "market contracts" to organize caregiving activities. The advantage of this choice lies in the fact that family members share long-term relationships, shared residual claims (parents' well-being is the children's well-being), and informal social sanctioning mechanisms (shame, guilt, community pressure).^[15]

V. Gift Economy vs. Market Economy: The Dual Logic of Care

Anthropologist Marcel Mauss, in his classic work The Gift, distinguished between two fundamentally different logics of exchange: the gift economy and the market economy.^[16]

In a market economy, exchange is settled immediately: I pay money, you provide a service, the transaction is complete, and neither party owes the other anything. The purpose of exchange is to acquire the goods or services held by the other party.

In a gift economy, exchange involves deferred reciprocity: I give you a gift, and you reciprocate at some future point. But the key is that the purpose of gift exchange is not to acquire objects, but to establish and maintain relationships. Mauss argued that a gift always carries the "spirit" (hau) of the giver — it is not merely an object, but a vehicle for relationships.^[17]

Care originally belongs to the realm of the gift economy. When adult children care for their aging parents, this act is a "reciprocal gift" for the parents' earlier nurturing — it is a link in the chain of intergenerational reciprocity.^[18] This reciprocal gift need not be equivalent, nor does it seek immediate settlement; its meaning lies in maintaining the continuity of family relationships.

When care is outsourced to the market, it transitions from the gift economy to the market economy. This shift creates several problems:

1. Commodification of relationships: Acts that originally carried relational meaning become commodities purchasable with money
2. Rupture of the reciprocity chain: The cycle of intergenerational reciprocity is broken — children "settle" their debt to their parents with money rather than continuing the relationship
3. Evacuation of meaning: The caregiving act loses its symbolic significance, becoming a purely functional service

Sociologist Arlie Hochschild further analyzed this phenomenon. She observed that modern society has witnessed an outsourcing of emotional labor.^[19] Emotional care once provided by family members — companionship, listening, consolation — can now be purchased on the market: therapists, companionship services, professional caregivers. But Hochschild warned that this outsourcing may lead to the "emotional hollowing out" of families.^[20]

VI. The Ethics of Care: Joan Tronto's Four Dimensions

Political theorist Joan Tronto and Berenice Fisher proposed a systematic framework for the Ethics of Care, decomposing care into four interrelated stages:^[21]

1. Caring about: Noticing that someone has a need for care
2. Taking care of: Assuming responsibility for meeting that need
3. Care-giving: The actual work of providing care
4. Care-receiving: The response and acceptance by the care recipient

Tronto noted that in the traditional model, these four stages are completed by the same group of people (usually family members), forming a complete "care cycle." But in modern society, these stages are frequently divided among different actors: children handle "caring about" and "taking care of" (recognizing that parents need care, deciding to hire a caregiver), professional caregivers handle "care-giving," and parents are the "care-receiving" party.^[22]

The problem this fragmentation creates is that the integrity of care is compromised. When "those who assume responsibility" and "those who give care" are separated, responsibility may be deflected and information may become fragmented. Children may think "I've already paid, my responsibility is fulfilled," while the actual quality of care goes unattended.^[23]

A deeper issue is that care is a relational practice.^[24] Its value lies not only in meeting the care recipient's needs but also in the bond formed between caregiver and care recipient. When this bond is replaced by market intermediation, the relational dimension of care is diminished.

VII. Kant vs. Utilitarianism: Why Does Intention Matter?

Why do we care so much whether care is "personal" or "outsourced," even when the outcomes may be identical? This touches upon the fundamental divide between deontology and utilitarianism in ethics.

The utilitarian position is: only outcomes matter. If outsourced care can deliver higher quality (more professional, more consistent, less fatigued), then outsourcing is the correct choice. Intention, motivation, who performs the care — none of these matter; what matters is the total welfare produced.^[25]

Kantian deontology takes the opposite stance. Kant argued that the moral worth of an action lies in the agent's maxim and will, not in the action's consequences.^[26] More importantly, Kant's Formula of Humanity demands: always treat persons as ends in themselves, never merely as means.^[27]

When children outsource care, a potential moral risk is that parents are treated as "problems" to be "handled" rather than as "ends" to be "respected." The logic of outsourcing is efficiency-oriented — achieving the functional goal of care with minimal personal investment. This logic risks "instrumentalizing" parents.^[28]

Of course, this is not absolute. A child who truly loves their parents may choose outsourcing precisely because they want "the best care for their parents" — this motivation itself is moral. But the issue is that motivation cannot be directly observed. Parents and society can only infer motivation from actions. And in the absence of other information, "personal caregiving" is regarded as more credible evidence of "love."^[29]

VIII. Cross-Cultural Comparison: Filial Piety, Welfare States, and the Eldercare Industry

Different cultures exhibit significant variations in their acceptance of care outsourcing. These differences can be explained through historical, institutional, and value-based perspectives.

The East Asian Confucian Tradition: Institutionalization of Filial Piety

In the Confucian cultural sphere (China, Japan, South Korea, Taiwan, Vietnam), filial piety is a core social norm. The Classic of Filial Piety explicitly states that caring for one's body and honoring one's parents through upright conduct constitutes the beginning and end of filial devotion.^[30]

Filial piety is not merely a personal virtue but a social institution. Traditional Chinese legal systems (such as the Qing Code) explicitly stipulated children's obligations to support their parents, and unfilial behavior was even a criminal offense.^[31] This institutionalization transformed "filial piety" from an intrinsic motivation into an external constraint, giving the label of "unfilial" extremely powerful social sanctioning force.

Within this framework, outsourcing care is seen as "cutting corners on filial piety." Even when children have legitimate reasons (busy work schedules, lack of caregiving skills), outsourcing still invites moral suspicion from society.^[32]

Nordic Welfare States: The Legitimacy of State-Provided Care

Nordic countries (Sweden, Denmark, Norway, Finland) have adopted a fundamentally different model. In these nations, eldercare is regarded as a citizenship right, provided by the state through taxation.^[33]

Why do Nordic people accept "state care" rather than insisting on "family care"? Several factors may explain this difference:

• Individualist tradition: Nordic culture emphasizes personal independence; elderly people do not wish to "become a burden on their children," and accepting state services is viewed as a way of preserving dignity^[34]
• High-trust state: Nordic people have high levels of trust in government institutions and believe that the quality of state-provided care is guaranteed^[35]
• Gender equality: Refusal to impose caregiving responsibilities on women (traditionally, caregiving work fell to daughters or daughters-in-law); state care is part of gender liberation^[36]
• High taxes for services: Nordic people pay among the highest tax rates globally and correspondingly expect the government to provide comprehensive services from cradle to grave

It is worth noting, however, that even in Nordic countries, a distinction remains between "state care" and "market care." Swedes may accept government nursing homes but may still be skeptical of the motives behind "private for-profit nursing homes."^[37]

The United States: Deep Penetration of Market Logic

The United States represents another model: eldercare is highly marketized, with nursing homes, assisted living facilities, and home care agencies forming an enormous industry.^[38]

The background of the American model includes:

• Geographic mobility: Americans frequently relocate across states; adult children are often thousands of miles from their parents, making personal caregiving physically unfeasible
• Market ideology: Trust in market solutions and skepticism toward government intervention
• Nuclear family structure: Multi-generational households are not the norm; elderly people living independently is considered normal

But the American model also exposes the problems of market-based care: nursing home scandals are frequent (abuse, neglect), quality varies widely, and costs are prohibitive (potentially exceeding ten thousand dollars per month), making them unaffordable for many middle-class families.^[39]

Taiwan: A Care System in Transition

Taiwan occupies an interesting inflection point. Traditional Confucian filial piety norms remain powerful, but rapid social changes (declining birth rates, rising female labor force participation, urbanization) have made the traditional model difficult to sustain.^[40]

The introduction of foreign caregivers (primarily from Indonesia, the Philippines, and Vietnam) has become a "compromise": families still bear caregiving responsibility (hiring, supervision, costs), but the actual caregiving work is performed by migrant workers.^[41] This model preserves the form of "family care" but raises new issues:

• Migrant worker rights: Working conditions, leave entitlements, and human rights protections for foreign caregivers
• Care quality: Language barriers, cultural differences, and lack of professional training
• Social stratification: Care becomes a class issue — the wealthy can afford good caregivers while the poor must manage on their own
• Moral ambiguity: Does this count as "fulfilling filial piety" or "shirking responsibility"? Social norms have yet to reach consensus

IX. Repeated Games and Family Cooperation: The Incentive Structure of Long-Term Relationships

From a game theory perspective, the family can be understood as a repeated game setting.^[42] Interactions among family members are not one-shot events but long-term relationships spanning decades. This characteristic profoundly shapes the incentive structure for cooperation.

Robert Axelrod's classic research demonstrated that in repeated prisoner's dilemma games, the Tit-for-Tat strategy can sustain cooperative equilibria.^[43] Applied to the family context: if a child does not care for their parents today, they may face in the future:

• Emotional alienation from parents and exclusion from inheritance
• Moral condemnation from siblings
• Reputational loss in the community
• "Retaliation" from their own children in old age (intergenerational tit-for-tat)

The Folk Theorem further states that as long as players are sufficiently patient (discount factor δ is sufficiently high), almost any feasible payoff combination can become an equilibrium in a repeated game.^[44] The long-term nature of the family makes cooperation possible, and "personal caregiving" is the concrete manifestation of this cooperation.

However, modern social changes are altering the structure of this game:

• Geographic mobility: Children and parents are separated geographically, reducing the frequency of repeated interactions
• Longer lifespans: The caregiving period may extend over a decade, dramatically increasing costs
• Social mobility: Community and neighborhood ties weaken, causing reputation mechanisms to fail
• Declining birth rates: Caregiving responsibilities concentrate on fewer children, intensifying the burden

When the conditions for the repeated game are disrupted, cooperative equilibria collapse. This perhaps explains why care outsourcing has become increasingly common in contemporary society — not because people have become "unfilial," but because the game structure has changed.^[45]

X. Mechanism Design: How to Preserve Signal Value in Outsourcing?

If care outsourcing is unavoidable in certain circumstances (or even optimal), then the key question becomes: How can we design institutions so that outsourced care can still transmit signals of "love"?

From the perspective of mechanism design, there are several possible directions:

1. Retain the "Taking Care Of" Role

Even when "care-giving" is outsourced, children can still actively participate in "caring about" and "taking care of" — through regular visits, monitoring care quality, handling emergencies, and participating in medical decisions. This demonstrates that outsourcing is a "choice" rather than an "evasion."

2. Increase Monitoring Costs as a Signal

Children can invest substantial time in monitoring — communicating with caregivers, reviewing care records, learning caregiving knowledge. While these investments do not constitute direct care, they are equally costly signals.

3. Transparency of Care Arrangements

Making parents and other family members aware of the reasons and trade-offs behind care arrangements. Candid communication can reduce suspicions of "shirking."

4. Renegotiation of Social Norms

In the long run, social norms need to be recalibrated to match real-world conditions. When most families face similar dilemmas, "outsourcing" may gradually be accepted as a legitimate choice — provided it is accompanied by genuine concern and oversight.

5. Repositioning the Role of the State

If society considers eldercare a public responsibility (rather than solely a family responsibility), then "using public care services" is no longer viewed as "unfilial" but as "exercising a citizenship right" — similar to the Nordic model.

XI. Declining Birth Rates and Population Aging: The Future Movement of Moral Boundaries

Taiwan's total fertility rate has dropped to 0.87, among the lowest in the world; meanwhile, the proportion of the population aged 65 and over is projected to exceed 20% by 2025, officially entering a super-aged society.^[46] This dramatic demographic shift will fundamentally transform both the economics and the ethics of care.

When the average couple has only one child while the number of elderly requiring care continues to grow, the mathematics of "personal caregiving" becomes impossible:

• A single child may need to simultaneously care for four grandparents and two parents
• If this child is also working (which they must, since the pension system depends on the working population's contributions), personal caregiving becomes physically impossible
• Gender inequality in caregiving will become even more acute — traditionally borne by women, but when women must also work, who will provide care?

Against this backdrop, the "moral boundaries" of care will inevitably shift. Future social norms may:

• Increasingly accept institutional and professional care as legitimate options
• View "monitoring" and "companionship" as new forms of filial piety, rather than insisting on "doing everything personally"
• Develop new signaling mechanisms to distinguish between "responsible outsourcing" and "evasive outsourcing"
• Redefine "good aging" — from "being cared for by one's children" to "independence and autonomy" or "community mutual aid"

Technological advances will also play a role: care robots, telemedicine, and smart home systems may partially replace human caregiving. But whether these technologies can transmit signals of "love" is a question that future societies must answer.

Conclusion: Understanding the Economics of Moral Intuition

The purpose of this article is not to judge whether "personal caregiving" or "outsourced care" is more moral — that judgment depends on specific circumstances, values, and cultural context. My aim is to explain why people hold such moral intuitions and the economic and sociological logic underlying them.

From the perspective of signaling theory, "personal caregiving" is considered a higher moral act because it is a costly and difficult-to-fake signal. From the perspective of contract theory, personal caregiving solves the incomplete contract and moral hazard problems that outsourced care faces. From an anthropological perspective, personal caregiving maintains the reciprocal logic of the gift economy, avoiding the commodification of relationships brought about by marketization.

But these logics are all context-dependent. When the game structure changes (declining birth rates, population aging, geographic mobility), when the information structure changes (better monitoring mechanisms), and when social norms change (redefinition of "good aging"), the moral boundaries of care will shift accordingly.

Ultimately, this is not an ethical question with a standard answer, but a social contract question that requires ongoing renegotiation. And understanding the sources of our moral intuitions is the first step in conducting that negotiation.
