Subsidiarity & Solidarity is a single principle with two halves, and neither makes sense without the other. Governing authority defaults to the most local competent level. Centralization bears the burden of justification. But membership in the political community means mutual obligation: when any part of the community faces a crisis beyond its capacity, the larger community has a structural obligation to respond with adequate resources. Authority is distributed. No community is abandoned.
Subsidiarity as Structural Allocation
Subsidiarity means that governing authority defaults to the most local level competent to exercise it. This is a structural allocation with legal force, not a norm, a preference, or a suggestion. The burden of justification falls on centralization: if a decision can be made effectively at the local level, it is made there, and the case for moving it upward must be affirmatively demonstrated.
The argument for subsidiarity is not merely that local governance is more efficient, though it often is. It is that local governance is more legitimate. The people closest to a problem are most likely to understand it, most directly affected by the outcome, and most capable of holding decision-makers accountable. A school board answerable to the parents in the district has a form of democratic legitimacy that a distant federal agency does not. A city managing its own land use knows the landscape, the community, and the trade-offs in ways that a state legislature cannot.
Subsidiarity also creates space for genuine diversity in governance. Different communities face different circumstances, hold different values, and have different needs. A continental polity that governs everything from the center must either impose uniformity on diverse communities or grant exceptions that become incoherent. Subsidiarity resolves this structurally: different communities can govern differently because authority rests with them by default. This is the insight behind Brandeis’s “laboratories of democracy,” stated with structural force rather than as a metaphor.
The States’ Rights Problem
Any American discussion of subsidiarity must confront the elephant in the room: “states’ rights” has been the primary rhetorical vehicle for racial domination throughout American history. The argument that authority should rest with local governments has been used, systematically and successfully, to maintain slavery, enforce segregation, suppress voting rights, and resist every expansion of civil rights from Reconstruction through the present day.
This history is not incidental. It reveals a genuine danger in any principle that distributes authority downward: local majorities can be tyrannical. Communities can use self-governance to oppress minorities within their borders. The closer the decision-maker is to the community, the more susceptible governance is to local prejudice, local power structures, and local enforcement of social conformity.
Subsidiarity & Solidarity is designed with this history built into its structure, not as an afterthought. This is not federalism with a new name. It is a principle that distributes authority and constrains how that authority may be used. The constraint is the Universal Human Rights floor, and it is non-negotiable.
The Rights Floor as Constraint
Subsidiarity operates above the Universal Human Rights floor. No level of government may breach it. This is the structural feature that separates subsidiarity from “local control” arguments that have historically served as cover for oppression.
The Rights Floor means that local authority over education does not include the authority to segregate schools. Local authority over policing does not include the authority to engage in racialized enforcement. Local authority over land use does not include the authority to deny housing on the basis of race, religion, or any other protected characteristic. The community’s right to self-governance is real and expansive, but it ends where fundamental rights begin.
Crucially, enforcement of the Rights Floor does not depend on the goodwill of local majorities. This is a design requirement, not a hope. A rights guarantee that can only be enforced when local power structures consent to enforcement is not a guarantee at all. The structural mechanisms for upholding the floor must be independent of the communities they constrain, while remaining democratically accountable themselves. This is difficult institutional design, but the difficulty does not excuse the failure to attempt it.
Solidarity as Structural Obligation
The second half of the principle is as important as the first. Subsidiarity without solidarity is abandonment with extra steps.
Membership in the political community means mutual obligation. When any part of the community faces a crisis beyond its capacity — natural disaster, ecological catastrophe, economic transition, displacement, public health emergency, or attack — the larger community has a structural obligation to respond with adequate resources. This obligation has several features that distinguish it from conventional disaster relief or federal aid:
-
It is not discretionary. The obligation is structural, not dependent on the political judgment of whoever holds power at the time. A community devastated by a hurricane does not wait for a leader to decide whether it deserves help.
-
It is not conditional on political alignment. Aid does not flow to political allies and away from political opponents. The solidarity obligation is owed to every part of the community regardless of how it votes, what party governs it, or whether its leaders have been sufficiently deferential to the central authority. Using disaster relief as political leverage is a violation of this principle, not a regrettable lapse in norms.
-
It is not a basis for overriding local authority. The larger community’s obligation to respond to crisis does not become a license to take over local governance. Aid comes with resources, not with a takeover. The community in crisis retains its authority over its own recovery, supplemented by the resources it cannot generate alone.
-
It scales with the crisis. “Adequate resources” means resources proportional to the need, not a fixed amount determined by political negotiation. The obligation is to actually meet the crisis, not to perform the appearance of response.
Fiscal Capacity Must Follow Responsibility
Subsidiarity without resources is not self-governance. It is abandonment dressed in the language of local control.
If authority over education is devolved to local communities, the fiscal capacity to actually educate children must follow. If public health responsibility rests with local government, the funding to maintain public health infrastructure must be available. The pattern of devolving responsibility while retaining resources at higher levels — the unfunded mandate — is a structural violation of this principle. It creates the appearance of local authority while ensuring that local governance fails, which then becomes the justification for further centralization.
The fiscal dimension also connects to Economic Democracy and the broader problem of wealth extraction. When concentrated wealth extracts resources from communities — through tax arbitrage, corporate relocation threats, or the simple outflow of capital from economically disadvantaged areas — it hollows out the fiscal capacity that subsidiarity requires. A community whose tax base has been gutted by decades of extraction cannot exercise meaningful self-governance regardless of what authority it formally holds. Subsidiarity requires not just the devolution of authority but the structural conditions under which that authority can be meaningfully exercised.
The Productive Tension
The tension between subsidiarity and the Rights Floor is real, and it is most acute in precisely the domains where governance matters most.
Education is the paradigmatic case. Local control of education is genuinely valuable: different communities have different needs, different cultural contexts, and different knowledge about what their children require. But local control has also been the mechanism through which schools were segregated, curricula were censored, and ideological indoctrination was imposed. The framework must hold both truths: local governance of education is legitimate, and it is constrained by the Rights Floor. The tension between them is not a problem to be solved but a dynamic to be governed.
Healthcare presents a similar tension. Healthcare delivery can be organized at different scales for different purposes — community clinics, regional hospitals, national standards and funding. Subsidiarity allows for this variation. But the right to healthcare is a floor guarantee: access to adequate care regardless of where you live, what level of government administers it, or what economic class you belong to. A system where healthcare quality depends on geography is a system where the Rights Floor has been breached.
Criminal justice adds another layer. Democratic Peace & Security requires that policing be democratically accountable at the level where it operates — a subsidiarity commitment. But local control of policing has been the mechanism through which racialized enforcement, political suppression, and community-specific brutality have been maintained. The Rights Floor constrains local policing authority; subsidiarity keeps it accountable to the community it serves. Both are necessary. The tension between them is the terrain on which just governance is built.
Solidarity and Wealth Inequality
Wealth inequality does not just trigger solidarity obligations; it manufactures the crises that create them. When concentrated wealth extracts resources from communities, hollows out their tax bases, eliminates their economic infrastructure, and then moves on, it produces the very conditions of crisis that the solidarity obligation is designed to address. The community left behind has not failed at self-governance. It has been stripped of the capacity to self-govern.
This means that structural limits on wealth accumulation are not merely an Economic Democracy concern. They are a precondition for subsidiarity to function. A system that permits unlimited extraction while relying on solidarity to clean up the wreckage is a system at war with itself. Solidarity responds to crisis; structural limits on accumulation prevent the manufacturing of crisis in the first place. Both are necessary.
Relationship to Other Principles
Plural Sovereignty distributes authority laterally, across different kinds of political community. Subsidiarity distributes it vertically, from local to central. Together they create a multi-dimensional allocation of governance: decisions are made at the right level and by the right communities, with neither axis reducible to the other.
Ecological Embeddedness makes solidarity obligations concrete in ways that geographic boundaries cannot contain. Ecological crises do not respect state lines. A wildfire, a drought, a contaminated watershed — these are solidarity triggers that may affect communities across multiple jurisdictions simultaneously, and the response must match the scale of the crisis, not the scale of the nearest political boundary. Ecological solidarity is one of the strongest arguments for robust mutual obligation across the polity.
Adaptive Capacity connects to both halves of the principle. Subsidiarity provides the diversity and local responsiveness that adaptive systems require — different communities trying different approaches, learning from each other, adapting to local conditions. Solidarity provides the resilience — no community’s failure cascades into systemic collapse because the larger system absorbs the shock and supports recovery. Together, subsidiarity and solidarity are the structural equivalent of a healthy ecosystem: diverse, locally adapted, and resilient because no part is left to fail alone.
