Charles Tilly analyzes how inequality becomes entrenched when organizations embed categorical boundaries in resources and opportunities. He also shows how people develop repertoires for collective action and make demands on those in power. His sociology shifts the focus from individual attitudes to mechanisms, relationships, and organized capacity.
Categorical Pairs and Persistent Inequality
In *Durable Inequality*, Tilly describes how organizations use categorical pairs—such as citizens and non-citizens, permanent and temporary employees, or men and women—to allocate work, rewards, and risk. These categories can be linked to pre-existing boundaries, thereby stabilizing inequality.
This mechanism does not require every participant to hold a deliberate prejudice. A routine can reproduce the difference simply because it is inexpensive, familiar, or benefits those who control the resources. Change must therefore target the category’s connection to opportunities, not just people’s attitudes.
Trace a category boundary through an organization
Purpose: To see how an everyday division is linked to resources, risk, and career.
Choose two formal or informal categories within an organization.
List differences in tasks, information, pay, job security, and influence.
Identify which rule or habit reproduces the difference in the next decision.
Examine whether the category is necessary for the task or has become a shortcut.
Propose a change in access, rotation, or criteria that breaks the link.
Afterward: The analysis reveals where inequality is produced, even when no one explicitly decides on its final scope.
Limitations and when the exercise should not be conducted: Use aggregated or authorized data and comply with anti-discrimination and labor law regulations.
Exploitation and the Accumulation of Opportunities
Tilly highlights two central mechanisms. Exploitation means that more powerful actors control resources and benefit from the labor of others while limiting their returns. Opportunity hoarding means that a group monopolizes a resource or means of livelihood and shares it primarily within its own network.
Opportunity hoarding can provide a vulnerable group with protection and survival, but it can also exclude others. The analysis must therefore examine both who controls the larger resource and how subgroups organize access to it.
Distinguish between exploitation and opportunity concentration
Purpose: To identify which mechanism keeps a resource unevenly distributed and thereby select the appropriate action.
Choose a resource or opportunity that is unevenly distributed.
Write down who controls the resource and who produces the value.
Examine whether a group restricts access through networks, licensing, inheritance, or informal recruitment.
Determine whether the primary mechanism is exploitation, accumulation of opportunities, or both.
Choose a course of action: redistributed returns, open access, representation, or collective organization.
Afterward: Different mechanisms require different responses. Open recruitment alone does not solve exploitation, and higher pay does not automatically open up a closed network.
Limitations and when not to do this exercise: Do not make legal allegations without evidence. Discrimination and labor law require professional review.
Imitation and Adaptation in Organizations
Persistent inequality spreads when organizations emulate models that already rely on categorical distinctions. It is also reproduced through adaptation: people develop everyday strategies around the existing order, so that many processes come to depend on the boundary remaining in place.
Consequently, a formal rule change may have less impact than expected. Schemas, relationships, and informal knowledge continue to perpetuate the old divisions. Sustainable change must take into account which practices need to be restructured and which stand to lose or gain from the transition.
Track what survives a rule change
Purpose: To identify informal adaptations that continue to reproduce a difference that has been abolished.
Choose a rule or policy that has recently been changed to promote greater equality.
Write down which old pattern the change was intended to break.
Observe routines, information flows, and informal choices following the change.
Identify where the old category is still being used as a shortcut.
Suggest a complementary practice and a follow-up to monitor actual distribution.
Afterward: A change is only truly implemented when everyday realities—not just the text of the rule—have changed.
Limitations and when the exercise should not be conducted: Do not single out individuals as opponents without evidence. Focus on mechanisms and consequences.
Repertoires, Claims, and Collective Capacity
Tilly describes repertoires of collective action: historically learned ways of making claims, such as meetings, demonstrations, petitions, strikes, and campaigns. Groups do not choose from every conceivable action; they use forms they are familiar with, that their surroundings understand, and that fit their available organizational capacity.
Collective advocacy becomes stronger when participants demonstrate dignity, unity, numbers, and perseverance. These signals cannot replace a reasonable demand, but they show that the claim is backed by an organized group. For a good life, people need pathways from private grievances to a secure and democratic voice.
Choose a collective repertoire that fits the goal
Purpose: To link a shared demand to a safe, understandable, and proportionate form of action.
Choose a specific demand that affects multiple stakeholders.
Identify who has the authority to make the decision you wish to influence.
List available forms of action, ranging from conversations and written correspondence to joining an organization or public action.
Evaluate each form based on risk, participation, visibility, and the possibility of follow-up.
Choose the minimum sufficient form of action and determine how participants will be protected and informed.
Afterward: A repertoire should increase the group’s capacity and bring the demand closer to the appropriate decision-making level.
Limitations and when the exercise should not be conducted: Adhere to the law, safety, and the principle of voluntariness. Do not expose people in vulnerable positions to public scrutiny or reprisals.
