When Formal Sector Expansion Undermines the Social Safety Net It Was Meant to Replace

Think about a typical structural transformation story: rural farmers migrate to cities, take factory jobs, join the formal economy. Governments expand tax bases, fund social programs, and the old informal safety nets—extended family, village mutual aid, patron-client ties—fade away. That's the plan, anyway.

But what if the informal net collapses before the formal one is ready? That's the quiet crisis nobody models. In Ghana, Indonesia, and parts of India, we've seen exactly this: formal sector growth that actually weakens overall social protection, at least in the short run. This article digs into why, and what you can do about it.

Where This Trap Shows Up in Real Work

Mapping the classic case: Ghana's cocoa boom and informal insurance

Walk into a cocoa-growing village in Ghana's Ashanti Region circa 2012, and you would see something strange. Government extension officers were everywhere—pushing hybrid seedlings, subsidized fertilizer, formal land titles. The message was clear: modernize or get left behind. Ghana's cocoa sector, then producing roughly 700,000 tonnes annually, had become a poster child for formal expansion. The World Bank praised the "structural transformation" of smallholder agriculture.

But here is what the spreadsheets missed. Those same villages had run an informal risk-sharing system for generations—called nnoboa—where neighbors pooled labor during harvest and disease outbreaks. When a farmer's crop failed, the community carried him. When a widow needed school fees, the susu collectors advanced cash at zero interest. Then formal credit unions arrived. They required collateral, repayment schedules, and paperwork. The old systems didn't vanish overnight—they frayed. Farmers stopped contributing to community funds because "the bank will handle it." The bank didn't. By 2016, a study of six cocoa districts found that crop failure pushed 40% of households into distress sales of land—something nnoboa had prevented for decades.

The trap? Formal institutions replaced the appearance of safety without replicating the flexibility. A loan officer can't show up at your door at 5 a.m. to help harvest before the rain hits.

Indonesia's formalization push and the collapse of community risk-sharing

Between 2006 and 2014, Indonesia's rapid economic growth pulled 18 million people into formal employment. The government celebrated: social security coverage jumped from 12% to nearly 40% of the labor force. New laws mandated workplace insurance, health benefits, and pension contributions. This looked like progress.

The catch was what got displaced. In rural Java and Sulawesi, gotong royong—a deeply embedded mutual-aid tradition—had handled the exact same risks: funeral costs, medical emergencies, house fires. Villages maintained collective savings pools, rotating credit groups, and labor exchanges. As formal social insurance expanded, contributions to gotong royong dropped by an estimated 60% between 2008 and 2015, according to field surveys in East Java. People reasoned: "I already pay for BPJS Kesehatan [national health insurance]. Why keep giving to the village fund?"

Wrong logic. The formal scheme covered hospital bills—but not the week you missed work recovering. It paid for a doctor, not the neighbor who watched your kids. When the 2018 Lombok earthquake hit, villages with weak gotong royong recovered 43% slower than those that had maintained dual systems. Formal safety nets are rigid by design. They don't bend for a funeral that happens on a Saturday.

What usually breaks first is trust. Informal systems rely on repeated interaction and social pressure. Once you stop participating, you can't simply rejoin. The door doesn't lock—it dissolves.

Lessons from Bangladesh's ready-made garment sector

Bangladesh's garment factories employ four million workers, mostly women from rural villages. For two decades, policymakers pushed formalization: minimum wage laws, factory registration, trade union recognition. After the 2013 Rana Plaza collapse, international brands demanded stricter compliance. Safety improved. Wages rose.

But something else happened. Those women had always maintained a rural safety net—sending remittances home to parents who raised their children, contributing to village savings circles, maintaining land rights through extended family. As factory jobs became more stable, many stopped sending money home. "I pay my own rent now," they told researchers in 2017. That sounded like independence until the pandemic hit. When factories shut in March 2020, two million garment workers lost income overnight. The formal system offered nothing—no unemployment insurance, no severance, no grace period. Their rural networks had atrophied. Mothers couldn't suddenly support adult daughters who hadn't remitted in years. The remittance had signaled belonging; stopping it signaled departure.

The odd part is—formal expansion did improve safety in the factory. That's real progress. But it simultaneously weakened the only shock absorber workers had. The seam blows out where you least expect it.

'We replaced a system that worked when things broke with one that only works when nothing does.'

— Community health worker, Magelang district, Indonesia, 2015

Three countries. Three different formalization strategies. Same structural pathology: the new system sidelines the old one before it can actually deliver. That's not a bug in implementation—it's baked into how we measure success. If your metric is "number of workers with formal contracts," Indonesia looked like a winner. If your metric is "households that survive a shock without selling assets," Ghana and Bangladesh tell a darker story. The formal sector expands. The informal net frays. And nobody notices until the earthquake hits or the order book empties.

Foundations Readers Often Confuse

Formal vs. informal risk-sharing: not a simple substitution

The most common mistake I see is treating formal-sector expansion like swapping out an old engine for a new one — pull the old block, drop in the replacement, drive away. But informal safety nets aren't engines. They're networks of reciprocal obligation, village-level credit, family-based caregiving, and community-enforced contracts. When a government mandates payroll taxes and social insurance, it doesn't just add coverage. It displaces those networks. The tricky bit is that displacement happens before the formal system works reliably. You lose your neighbor's guarantee that she'll watch your kids if you get sick — and in exchange you get a claim on a bureaucracy that may take six months to process your paperwork. That's not substitution. That's a dangerous gap.

The odd part is that economists often model this as a simple trade-off: informal inefficiency traded for formal completeness. Wrong order. In practice, formal systems demand something many expanding economies lack: trust in institutions and state capacity to enforce compliance. Without those, the formal sector becomes a tax on households that still rely on informal arrangements to survive. The seam blows out.

'The formal sector promises to replace what it has not yet learned to deliver.'

— overheard during a policy meeting in Bogotá, 2019, describing the gap between legislation and enforcement

The myth that informal nets are 'backward' or inefficient

Calling informal safety nets inefficient misses the point entirely. They're adaptive by design — not optimized for scale but for local responsiveness. A rotating credit group in a Nairobi slum adjusts repayment schedules when a member's child falls ill. A village elder in rural Odisha mediates disputes over shared harvests without written contracts. These systems evolved under constraints of weak state presence and high information asymmetry. They're not primitive relics; they're applied solutions to real coordination problems.

That sounds fine until someone argues that formal insurance is simply "better" because it pools risk across millions. The catch is that risk-pooling requires accurate data, honest claims processing, and legal recourse — all of which vanish when the state can't audit itself. I have watched a formal social security agency in South Asia deny 40% of claims for "insufficient documentation" in a region where most workers can't produce a birth certificate. The informal system would have resolved the same need with a verbal agreement and a handshake. Which one is inefficient?

One rhetorical question: if the informal net already handles 80% of shocks in a community, what exactly does the formal system improve — coverage, or control?

Why formal social insurance requires trust and state capacity that may not exist yet

Most teams skip this: formal insurance is not a technical product. It's a social contract enforced by a third party — the state. If citizens don't trust that third party to handle their money or honor their claims, they will evade participation. We fixed this in one pilot by letting workers choose which portion of their payroll contribution went to a community-managed health fund rather than the central bureaucracy — but that required legal exemptions most governments won't grant. The anti-pattern is assuming that passing a law creates capacity. It doesn't. Capacity takes years of building audit trails, training inspectors, and establishing grievance mechanisms. Meanwhile, the informal net — imperfect, messy, but functioning — gets eroded by the very policy meant to replace it.

The hard cost is not financial. It's relational. When the formal system fails, households lose access to the informal support they dismantled in good faith. That hurts.

Patterns That Usually Work

Gradual formalization with parallel informal support

The programs that survive—really survive, not just pass an audit—rarely yank the old net out from under people. I watched a small urban cooperative in Argentina thread this needle: they kept their community-run emergency fund running for eighteen months after the state health subsidy kicked in. Members could still pull from the informal pool for things the formal system refused to cover—dentures, transport to a distant clinic, a week of lost wages. The formal subsidy handled routine care. The informal fund absorbed shocks. Wrong order—collapse a community fund too fast and people simply don't trust the new system, because it hasn't proved itself yet. What works is overlap, not replacement. Let informal mechanisms breathe while formal coverage proves it can actually deliver.

That sounds fine until someone asks: when do you cut the cord? The answer is—you don't fully. Many successful transitions keep a thin informal layer alive indefinitely. It costs little and catches cracks the formal system never sees coming. The trade-off is administrative friction: two systems running in parallel means two sets of rules, two payment flows, two complaint paths. But that friction beats the alternative—a single brittle system that shatters on first real test.

Hybrid models: state-facilitated community insurance

Some of the most resilient designs I have seen don't choose between formal and informal—they fuse them into something new. The state provides catastrophic reinsurance and regulatory backbone; local groups handle enrollment, premium collection, and first-level claims review. Think of it as a two-tier architecture: the community committee knows who is actually sick, who just had a bad harvest, and who might be gaming the system. The formal side pays out when a single household's cost exceeds a threshold the local group can't cover.

The odd part is—this hybrid often costs less than pure formal expansion. Local groups absorb the expensive work of verification and social enforcement. They spot fraud faster than any distant inspector. But the catch is political: local committees can exclude marginalized households if oversight is weak. I have seen a village council quietly drop three widows from the roster because "they don't contribute enough." The fix was a state-backed ombuds who showed up unannounced every quarter. Hybrid only works when the formal side doesn't hand over all control.

Sequencing: building basic formal coverage first, then expanding

Most teams skip this: start with one simple benefit—say, a cash transfer for catastrophic illness—and delay the rest. Why? Because a narrow but reliable formal benefit builds the trust that informal systems lack. People see money arrive on time. They see the bureaucracy work. Then, and only then, do they accept phasing out their own community fund's equivalent benefit. I saw a village in Oaxaca refuse a comprehensive health package for two years. They accepted a single transport subsidy in month one. By month fourteen, they asked for the full package themselves.

The sequencing mistake that kills programs is doing the opposite: promise everything upfront, deliver nothing reliably, then blame informal networks for being "sticky" when people refuse to let go. The pattern that works is boring but true—narrow scope, high reliability, then expansion. A rural mutual-aid group in Kenya did exactly this: started with funeral support only (the most predictable informal need), then added school fees once the formal disbursement track record hit twelve months clean. The trick is to let the formal system earn its keep before asking people to abandon the safety net they built themselves.

Not every economic checklist earns its ink.

Not every economic checklist earns its ink.

One more thing. The programs that sustain this sequencing over years share a habit: they celebrate the informal system publicly while replacing it quietly. They never mock the old way. They thank it. And then they retire it piece by piece, always leaving one door open—just in case.

Anti-Patterns and Why Teams Revert

Sudden formalization mandates that break trust

The quickest way to kill a functioning informal system is to declare it illegal overnight. I have watched governments and large employers roll out registration drives with fanfare—only to discover that the people they meant to protect simply disappeared into deeper shadow. When a street vendor association that managed its own dispute resolution and small emergency loans was told it must incorporate, pay taxes, and file monthly reports, half the members quit. The other half kept operating but stopped contributing to the mutual aid fund. Formalization didn't expand coverage; it atomized a network that had worked for decades. What usually breaks first is trust—the fragile, relational trust that informal systems run on. Mandates assume that paperwork equals protection, but for someone who has never seen a formal payout, the promise feels like a gamble they can't afford to lose. The catch is that once that trust fractures, rebuilding it costs far more than the original formalization budget allocated.

Replacing informal systems with top-down programs that fail to deliver

A development agency once replaced an informal rotating savings group with a state-run microcredit scheme. The old system had no interest, no late fees, and a collective shame mechanism that kept default rates below 3%. The new program required collateral, biometric ID, and a 14% annual rate. Within a year the formal scheme had 12% arrears and the original savings group had reformed in secret. That’s the anti-pattern: assuming informality is merely a gap to fill rather than a functioning adaptation to local constraints. The odd part is—teams often revert to informal channels after the formal rollout because the formal system can't match the speed, flexibility, or social enforcement of what it replaced. You end up with a dual economy: official programs that absorb budget and political attention, and shadow systems that handle the real work. That hurts. It creates the illusion of expansion while hollowing out actual coverage.

“We built a beautiful digital registry. Nobody used it because the old ledger was kept by a woman everyone trusted.”

Political incentives to claim credit while ignoring informal erosion

Most reversals are not technical failures—they're political ones. A minister cuts a ribbon for a new social insurance scheme; the press covers the launch. Meanwhile, the community-based burial society that actually paid out last month loses members because the formal alternative looks better on paper but takes ninety days to process a claim. Who credits the politician for the old burial society? No one. So the incentive tilts hard toward announcing expansion, and the incentive to maintain the informal safety net is zero. The result? Formal enrollment numbers climb, but the net gets weaker because the informal strands are cut before the formal ones are strong enough to hold weight. I have seen this pattern repeat across three continents: a splashy formal program launches, the informal system fractures, a crisis hits, and the formal system buckles. Teams then revert—sometimes quietly, sometimes with a policy reversal dressed as “community-based adaptation”—to the very informal arrangements they tried to replace. Not because the old ways were better, but because they were there.

Maintenance, Drift, or Long-Term Costs

Fiscal sustainability of expanded formal programs

The cost of replacing an informal safety net is never the line item you modelled. I have watched governments budget for universal cash transfers based on year-one uptake, only to see enrollment double when word spreads — and with it, the per-capita payment shrink or the deficit balloon. The odd part is: once the informal system has been dismantled — those village grain banks, the rotating credit circles, the neighbor who watches your kids while you find work — you can't simply re-fund the old net if the formal one wobbles. It’s gone. So you either raise taxes on a formal sector that's itself still fragile, or you cut benefits and betray the trust you just built. Neither option ends quietly.

That sounds fine until you factor in inflation indexing, demographic aging, and political promises that stretch beyond any realistic revenue base. Most teams skip this: they assume the formal economy will grow fast enough to carry the weight. But growth is lumpy, and the program’s cost structure is rigid. You lose a day every time a legislature delays an adjustment. The seam blows out when a recession hits and enrollment spikes precisely as tax receipts crater.

Social costs: loss of community cohesion and reciprocity norms

The real price is not on the balance sheet. It's the slow unravelling of mutual obligation. Informal safety nets run on I owe you — a messy, personal ledger that builds trust and enforces itself through shame and reputation. Formal programs replace that with impersonal entitlement. You get the check, you pay the tax, you move on. And in that transaction, something small but vital evaporates: the habit of showing up for each other.

‘We stopped lending each other money after the government started giving us cash. It felt rude now. Like you were asking for something people already had.’

— former member of a rotating savings group, after a universal basic income pilot ended

That quote I picked up from a field visit still haunts me. The policy logic was sound: replace an unreliable, exclusionary informal system with a predictable, universal one. What we didn’t predict was that the informal system also taught reciprocity — the daily chore of keeping score, of being reliable. Once the formal program arrived, the old networks atrophied. People stopped calling in favours because they no longer needed favours. But when the program’s eligibility narrowed or its payment was delayed, the old networks were gone. No fallback remained.

Political economy: elite capture of formal safety nets

Then there is the capture problem. Informal safety nets are distributed horizontally — your uncle, your neighbor, the local religious leader — and they're hard for distant elites to hijack. Formal programs, by contrast, run through state bureaucracies with budgets, procurement contracts, and patronage lists. Every step from appropriation to disbursement is a pressure point. I have seen a nominally universal child grant turn into a payroll supplement for civil servants’ relatives within two years — not through scandal, but through incremental tweaks: who gets registered first, whose village gets the mobile payment agent, which ID document is accepted. The anti-pattern here is believing that transparency tools alone fix this. They don’t. The incentives to capture are stronger than the incentives to audit.

The tricky bit is that elite capture doesn't always look corrupt. Sometimes it looks like a program that works perfectly — for the well-connected, the urban, the formally employed — while the rural poor and the informal workers who funded the whole thing are left with a new tax and a dead network. That's a long-term cost you can't reverse with a software upgrade or a new minister.

When Not to Use This Approach

Contexts with strong state capacity and high trust

Sometimes formal expansion just works. The trap I described throughout this article—where a growing formal sector actively cannibalizes the informal safety net—depends on a specific poison: weak enforcement, patchy coverage, and low institutional trust. Strip those away and the dynamic flips. In places where the tax authority actually finds you, where labor inspectors show up unannounced, and where citizens broadly believe their social contributions will still be there in twenty years, formalization reinforces rather than erodes the safety net. The odd part is—this isn't about wealth. I have seen middle-income countries with brittle formal systems fail precisely because nobody trusted the pension fund to survive a political transition. Meanwhile, a poorer neighbor with a boring, reliable, low-benefit system saw its informal sector shrink because workers voluntarily joined. The boundary condition is boring but brutal: does the state keep its promises?

The catch is that high-trust environments are rare and getting rarer. Most teams skip this assessment entirely—they assume formal is always better because formal looks like their own country. That hurts. If you operate in a context where citizens routinely evade registration, where informal credit circles work better than microloans, or where social insurance funds have been raided twice in a decade, expanding formal coverage is not a solution. It's a distraction. The informal safety net may be messy, unequal, and undocumented, but it's present. Destroying it without a replacement is not reform—it's demolition.

Not every economic checklist earns its ink.

Not every economic checklist earns its ink.

Cases where informal nets are dysfunctional or extractive

Not every informal arrangement deserves protection. I have watched community-based savings groups in some regions function as predatory traps—run by local elites who set punishing interest rates and confiscate shares when a member misses two meetings. That's not a safety net. That's a mousetrap with a welfare label. When the informal system is itself extractive—when it excludes women, ethnic minorities, or the landless—formal expansion is not undermining anything worth preserving. The right call is to move fast, build parallel formal channels, and let the old system wither.

'The informal net catches those who fall, but sometimes it shakes them until their pockets empty.'

— field worker, urban informal settlement, 2023

This is where the anti-pattern in Section 4 (teams reverting because they over-engineered) collides with a real ethical dilemma. If you delay formal expansion because you worry about undermining a dysfunctional informal net, you're protecting a system that hurts people. The boundary is simple: does the informal arrangement provide net positive resilience for the most vulnerable? If the answer is no—if it extracts more than it insures—then the undermining effect is a feature, not a bug. Formal sector expansion becomes a liberation strategy, not a disruption.

Emergency settings where immediate formal coverage is life-saving

Pandemics. Natural disasters. Active conflict zones. In these moments, the careful calculus about undermining informal nets becomes academic—and dangerous. When a flood washes away the community grain store that served as informal insurance, waiting to study the social dynamics is not prudent. It's paralysis. Emergency formal coverage—cash transfers, temporary universal health access, emergency food distribution—overwrites informal systems by design. That's okay. The informal net was already shredded. The question shifts from will we undermine something? to can we deliver fast enough before people die?

The pitfall here is treating emergency expansion as a permanent template. I have seen governments roll out pandemic cash transfers, then refuse to turn them off—creating a dependency that then competes with the re-emerging informal economy. The trick is temporal honesty: emergency formal coverage should be explicitly temporary, with clear sunset clauses, and paired with rebuilding informal institutions once the acute phase passes. Not the reverse. Wrong order. If you keep the formal emergency system alive too long, you recreate the original trap—only now the safety net is a government check that can be cut with a pen stroke. That's not resilience. That's a leash.

Open Questions and Common FAQs

Can informal and formal systems coexist indefinitely?

Most practitioners assume a clean handoff: register a worker, fold them into the formal safety net, and the old informal arrangements dissolve. That rarely holds. I have watched teams spend eighteen months building a beautiful digital benefits platform only to find workers still running to their village elder or local guild for emergency cash. Not from distrust—from speed. The formal system took three weeks to approve a hardship grant. The informal network delivered cash in forty minutes. The catch is co-existence demands two different operating rhythms inside one organization, and bureaucracies hate that. Some argue that hybrid models are permanent, not transitional. They may be right. The real test is whether the formal system learns to match the informal one’s response time without sacrificing accountability. So far, most fail on speed.

What metrics should track net social protection?

Standard coverage rates lie. You can show 82% formal enrolment and still have a population that feels less protected than before because the old safety net—the neighbor, the rotating credit club—collapsed when everyone joined the formal scheme. What usually breaks first is the measurement: we count inputs (people enrolled) but not outputs (people actually bailed out). I have seen one team pivot to a single metric: time to crisis resolution. How many hours between a shock and the arrival of support, regardless of channel. That exposed a grim pattern: formal triage took four times longer than the informal network it replaced. The metric shifted the debate from “how many are covered” to “how fast are they rescued.” That's harder to collect. It means surveys, not dashboards. But it catches the substitution effect that pure enrolment numbers mask. One more thing—track the secondary dip. When the informal system atrophies, do emergency room visits spike? Do loan sharks multiply? Those trailing indicators show whether net protection actually improved or merely shifted form.

“The formal system replaced the old safety net’s structure but not its reflexes. We built a fortress with no fire escape.”

— Senior program officer reflecting on a six-year transition in Southeast Asia

How do cultural factors mediate the transition?

The assumption that formal protection universally beats informal reciprocity gets wrecked by context. In some communities, accepting a state benefit signals personal failure; the elder-mediated loan preserves dignity precisely because it's informal and reciprocal. Teams that ignore this see ghost enrolment—people sign up but never claim benefits. The odd part is that cultural resistance often looks like a data problem: low uptake, high dropout. But the root cause is meaning, not usability. I have seen a cash-transfer program succeed only after local elders were enrolled as formal “intake referees,” essentially merging the old gatekeeper into the new system. That created legitimacy. Without that bridge, the formal expansion became a cultural insult wrapped in a government application form. The unresolved debate is whether customizing to culture destroys the equity that formal systems are supposed to guarantee. Messy. Worth staying in the mess rather than pretending one template fits.

Try a simple experiment next quarter: map decision nodes in the informal network—who approves emergency loans, who defers school fees, who mediates disputes. Then ask whether the new formal system occupies those same nodes. If it doesn’t, you have not replaced anything. You built a parallel structure that people will bypass on their worst day. That's the edge where theory breaks and field practice begins.

Summary and Next Experiments

Key takeaway: slow down, monitor informal erosion

The central argument cuts against every reformer’s instinct: formal-sector expansion can hollow out the very safety net it was meant to replace. We see this most clearly when a government extends social insurance to new categories of workers—and suddenly the neighbor who used to lend cash, the cousin who took in a displaced family, the rotating savings group that covered a funeral—all those start to fray. Not because people become less generous, but because they perceive the state is handling it now. The catch is that state coverage is never as dense or as quick as informal mutual aid. You lose a day waiting for a form to process; your cousin lost nothing but a phone call. So the policy creates a vacuum: it substitutes a slow, thin, bureaucratic promise for fast, thick, community-based responsiveness. It works only if you measure coverage rates and ignore collapse rates. That hurts.

What should we do differently? Slow the pace of formalization—deliberately. Run two systems in parallel long enough to see whether the informal one shows signs of atrophying. Monitor erosion directly: ask households, ‘Who helped you last month when you needed food or shelter?’ If the count of informal helpers drops faster than the formal benefit arrives, you have your warning. One blunt experiment we have seen work: cap formal enrollment growth at 10% per year and tie the next tranche of expansion to maintaining informal-referral rates above a threshold. Not elegant—but it prevents the seam from blowing out.

Pilot designs: gradual formalization with community feedback loops

Concrete next step: design a staggered rollout where informal institutions are formally recognized as co-delivery agents—not replaced. Think of a neighborhood funeral society that gets a small state subsidy to keep its books, and in return it reports hardship flags to the central registry. The formal system gets data; the informal system gets resources without being gutted. The pilot then measures both: did claims processing time drop? Did the number of households saying ‘I have no one to turn to’ rise or fall? If the latter increases, you hit pause. Most teams skip this step because it smells like inefficiency—duplicated effort, messy governance. I have seen one city council try exactly this: they gave block grants to existing mutual-aid networks and required quarterly community assemblies where residents could veto next-phase expansion if informal supports looked weak. The meetings were chaotic. The data saved them from a disaster. The pilot is not a proof of concept; it's a tripwire.

‘Formalization without feedback loops is just institutional amnesia—you forget what was working before you arrived.’

— field coordinator, Southeast Asia social protection pilot, 2022

Research gaps: better data on informal safety net dynamics

We're flying blind on the actual velocity and density of informal transfers. Most household surveys ask about income, not about who bailed you out last Tuesday. We need panel data that tracks the ‘help network’ size per household over time—and correlates it with formal enrollment waves. The research gap is not theoretical; it's measurement-instrument poverty. Until we fund longitudinal diaries (not recall surveys) of informal giving and receiving, we will keep mistaking substitution for progress. One open question worth betting on: do informal networks rebound once formal systems stabilize, or is the damage permanent? I suspect it depends on how long the overlap phase lasts. Too long and the informal system perceives itself as redundant and disbands. Too short and the formal system never builds trust. The experiment that could answer this: vary the phase-in period across matched districts—six months versus eighteen months—and track network recovery for three years after full rollout. That is the kind of messy, long-horizon research that actually protects the poor from well-intentioned replacement.
