You ever notice the one place we all agree to suspend the whole class taboo is at thirty-five thousand feet. First class, business, premium economy, economy. Curtains, separate boarding lanes, lounges behind frosted glass. Nobody blinks.
The boarding pass is the last surviving sumptuary document in the West.
That's exactly the thread Daniel's pulling on. He wrote in with a whole thing about how stratifying a society by income or education is considered uncouth, a relic, something you don't say out loud. But airlines do it openly, as a product feature. And he wants to know why that back door exists. Then he points to the Indian caste system as the strongest modern case of a society where caste is a living construct, not a museum piece. He asks what other examples survive, and how history handled external markers of class, the stuff placed on people, as he put it. And how all of that differs from the loose working class, middle class language we use in economics.
So he's asking three things at once. Why the taboo, what's still standing, and what the old machinery looked like.
Right. And the thing that makes it hang together is a distinction I don't think we name often enough. There's class as description, and class as assignment. Let's start with the taboo itself, why it's rude to say class out loud, and why a boarding pass gets a pass.
The taboo is real, and it's recent. Post-war meritocratic consensus. You dismantle hereditary titles, you pass civil rights laws, you build a story that says your position is achieved, not ascribed. You worked for it. You earned it. And in that story, any formal category that assigns you a rank at birth is embarrassing. It contradicts the whole premise.
So we describe class instead of assigning it. Working class, middle class, upper middle. Those are analytic terms, sociological shorthand. They're contested, fuzzy, and nobody has to carry a card.
And notice how those terms all gesture at fluidity. You can move from working class to middle class in a generation, or in a decade if the job market cooperates. The language is built to accommodate movement, because the meritocratic story needs movement to be possible.
But here's the thing. That fluidity is real but it's also a story we tell ourselves. The data on intergenerational mobility in the West is not exactly a rocket ship. Most people stay pretty close to where they started.
Right. The language promises more movement than the structure delivers. But the promise is the point. The language has to keep the possibility alive, even if the statistics are stubborn.
So the descriptive terms are doing ideological work. They keep the meritocratic story intact by keeping the categories soft. Nobody has to carry a card, which means nobody has to confront the fact that the card might as well exist.
And that's exactly what the airline refuses to do. The airline doesn't pretend. It sells you a tier. It's legally explicit, visibly enforced, and inherited for the duration of the ticket. You board in group one or group five. You turn left or right at the door. The curtain closes behind you.
And it's marketed as a product. That's the back door Daniel spotted. The airline isn't saying you're a better person. It's saying you bought a better seat. The class is temporary, voluntary, and paid for. Which makes it acceptable in a way that an inherited rank never would be.
But the structure is identical. Who boards first, who waits where, who gets the hot towel. The airline regulates access with the same quiet efficiency as any old sumptuary code. It just calls it a fare class instead of a social order.
There's a moment I love in this. You're standing at the gate, and the agent calls Group One. Half the room doesn't move. Then Group Two. Still nothing. And you realize the entire waiting area is a sorting mechanism. The seats are arranged so you can see who gets up first. It's a performance of rank.
And everyone watches it. You can't not watch it. The boarding process is a public ceremony of stratification. It's the modern equivalent of a procession, where the order of entry tells you exactly where you stand.
But it's not just the boarding. It's the whole architecture of the airport. The lounge behind frosted glass. The priority security line. The pre-boarding area with the nicer chairs. You walk past all of it on your way to the gate. The airport is designed to show you what you're not getting.
The curtain between cabins is the modern equivalent of the forbidden fabric. Instead of telling you what you may wear, the airline tells you where you may sit, board, and wait. And it enforces it with a scanner and a boarding group.
So the taboo is about ascription, not about hierarchy. We don't mind hierarchy. We mind being told it's assigned rather than chosen. The airline gets away with it because the assignment is temporary and framed as a purchase. That's the opening move. Now let's go to the hard case. Airlines sell you a temporary class. What happens when the class you're born into is the one that structures your whole life?
That's caste. And the first thing to get straight is that the Indian caste system is not one monolithic hierarchy. It's two systems layered on top of each other. Varna and jati.
Distinguish them.
Varna is the ancient textual model. Four categories. Brahmin, Kshatriya, Vaishya, Shudra. Priests, warriors, merchants, laborers. And then outside the system entirely, the Dalits, formerly called untouchables. That's the ideology. The cosmology. It's in the texts, it's clean, it's four plus one.
But it's not how daily life actually works.
Right. Daily life runs on jati. Thousands of endogamous local birth-groups. Endogamous meaning you marry within the group. Jati is the operating system. It determines who you can marry, who you can eat with, sometimes who you can do business with. It varies enormously by region. A jati in Tamil Nadu and a jati in Uttar Pradesh don't map onto each other neatly.
So varna is the story the system tells about itself, and jati is the machinery.
And the machinery is marriage. Endogamy reproduces the boundary more effectively than any law could. You don't need a statute saying marry within your group if every family enforces it socially. The group persists because the boundary is reproduced every generation.
So caste is ascribed at birth, externally identifiable in many contexts, and reinforced by the one institution that actually perpetuates a community. That's the mechanism.
And it's not merely economic. That's the thing that breaks people's mental model. A poor Brahmin and a wealthy Dalit both exist. Caste is not income. It's not education. It's a birth-group with social and ritual dimensions that money doesn't dissolve.
And the Indian state doesn't pretend it's not there. The reservation system is the state's explicit, legally codified acknowledgment of caste categories. Scheduled Castes, Scheduled Tribes, Other Backward Classes. Quotas in education and government employment.
Affirmative action on a scale that dwarfs anything in the West. Hundreds of millions of people fall under those categories. The state has to classify people by caste to run the program. So caste is not a folk memory. It's an active administrative category.
And there's a very current flashpoint. The University Grants Commission issued regulations this year on caste discrimination in higher education. And the Supreme Court stayed them.
That stay is significant. You have the executive and the regulatory apparatus trying to address caste discrimination on campuses, and the court says hold on, let's examine this. The legal contestation is live. This is not a relic. This is an active site of political and legal struggle in twenty twenty-six.
Which should complicate anyone's story that caste is fading away with modernization. It's modernizing. It's litigated. It's administered. It's not dissolving.
And the misconception to bust is that this is uniquely Indian. Caste-like structures have existed elsewhere. The Cagot are the case I always come back to.
Cagot. Basque and Béarn regions, France and Spain.
A caste-like group, subject to endogamy, occupational restriction, and spatial segregation. They were forbidden from certain churches, certain cemeteries, certain professions. They had to sit in separate pews, sometimes enter through separate doors. They were marked as different, and the difference was inherited.
And this lasted until the French Revolution and beyond.
The Revolution formally abolished the legal disabilities, but social exclusion persisted well into the nineteenth century in some areas. The point is that Europe had its own version of a birth-ascribed, externally marked, endogamous group. It wasn't as elaborate as the Indian system, but the mechanism was the same.
So when we say caste, we're not naming an Indian peculiarity. We're naming a type. Ascribed at birth, enforced by marriage rules, marked in public space, and justified by a story about purity or pollution or simply difference.
The Cagot case matters because it breaks the exoticism. You don't need Hindu cosmology to produce a caste-like structure. You need endogamy plus social sanction plus a visible marker. That combination shows up independently.
And in India it's the strongest modern case because all three are still operating at scale, with the added layer of constitutional democracy and affirmative action law on top. The system is being administered and contested, not just inherited.
Which brings us to the history Daniel asked about. The external identifiers. The stuff placed on people. Throughout history, societies marked class on the body and in daily life. Sumptuary laws are the cleanest example.
Medieval and early modern Europe. Laws regulating who could wear which fabrics, colors, furs.
Ermine for nobility. Certain dyes restricted. In some places, only the top ranks could wear purple or scarlet. The law didn't just describe your rank. It dressed you in it. You could be fined or punished for wearing above your station.
So the external identifier was literally on your back. And the law's job was to make sure nobody could fake it.
Which is the same logic as the airline checking your boarding pass before you cross the curtain. The marker has to be verifiable.
There's a fun fact here that I can't let go. In Elizabethan England, there were sumptuary laws that restricted the wearing of silk to certain ranks. But the law kept having to be reissued, because merchants kept finding ways around it. They'd line a cloak with silk instead of wearing it on the outside. The marker had to be visible, so the law had to chase the loopholes.
That's the arms race. The marker gets hidden, the law gets more specific, the marker gets hidden again. The state is always trying to keep the legibility intact.
Tokugawa Japan ran a four-tier system. Samurai, farmers, artisans, merchants. The shi-no-ko-sho order. With dress and residence rules.
And the merchants were at the bottom of the formal order, despite accumulating wealth. That's another reminder that these systems are not just economic. The merchant class had money but low formal rank. The samurai had rank but often little cash. The system assigned status independently of wealth.
So the external markers were doing real work. They told you who to bow to, where you could live, what you could wear, regardless of what was in your purse.
Colonial Latin America produced something even more explicit. The casta paintings. Literally a visual taxonomy of racial and class mixtures. Spanish father, Indigenous mother, the child is a mestizo. Spanish father, African mother, the child is a mulato. And on and on, dozens of categories, each with a label and a painted example.
They painted the hierarchy. A family tree where every branch is a rank.
And the paintings were commissioned by colonial elites, sometimes sent back to Spain to show the complexity of the social order in the colonies. They're documents of a society trying to make its stratification legible. Which is exactly what a class system needs. Legibility.
Legibility. That's the word. A class system only works if you can tell who's who. The marker has to be visible, or at least verifiable on demand. The sumptuary law made it visible. The casta painting made it legible. The boarding pass makes it scannable.
And here's the synthesis. The difference between describing class and assigning it. Working class and middle class are descriptions. They're analytic, contested, and they don't determine anything operationally. Nobody checks your working class card before you buy a sandwich.
But caste, sumptuary law, the Tokugawa tiers, the casta system, airline cabins, those are operational. They determine who sits where, who marries whom, who boards first, who gets the hotel voucher when the flight cancels.
Description versus assignment. That's the through-line. The descriptive terms are fuzzy because they're tools for analysis. The assigned categories are sharp because they're tools for allocation.
And the taboo exists because assignment is embarrassing to the meritocratic story. But the market found a workaround. Sell the assignment as a purchase. Make it temporary. Make it voluntary. Now it's not a social hierarchy, it's a menu.
And the menu hides something. The underlying stratification that lets you buy the first class ticket is often inherited and structural. The airline doesn't ask how you got the money. It just sells you the tier. So the temporary, voluntary class is built on top of a more durable one that nobody names.
Caste and sumptuary law are honest about being systems of assignment. The airline pretends to be a menu. That's the difference Daniel's pointing at, whether he knew it or not.
The airline is the modern heir to sumptuary law, but it's got better marketing. Instead of regulating what you may wear, it regulates where you may sit, board, and wait. And it enforces it with the same quiet efficiency. The curtain between cabins is the modern equivalent of the forbidden fabric.
So what's the difference between describing class and assigning it? That's the question underneath all of this. And the answer is that description leaves room for movement, and assignment doesn't. Working class is a place you can leave. A jati is a group you're born into and marry within. A fare class is a place you buy your way into for six hours.
The second-order implication is that the taboo is not about hierarchy. We love hierarchy. We queue for it at theme parks. We pay for it in software subscriptions. We upgrade to it on flights. The taboo is about ascription. About being told the rank was handed to you rather than chosen.
That's why the Indian case is so instructive. Caste persists alongside a modern constitutional democracy. Legal equality and social stratification coexist indefinitely. The constitution abolishes untouchability. The state runs affirmative action by caste category. The courts stay regulations on campus discrimination. All of it at once.
The arc of history does not bend toward the dissolution of ascriptive class. It bends toward the renegotiation of it. Caste becomes a legal category. It becomes a political identity. It becomes a basis for claims on the state. That's not dissolution. That's modernization.
The airline shows the other path. Ascriptive class becomes a product. You don't inherit it. You purchase it. But the structure, who gets served first, who waits, who gets the voucher, that's the same structure the sumptuary laws enforced.
The vocabulary changes. The allocation doesn't.
Hilbert: Pax tier.
What.
Hilbert: That's what the computer field was called. Pax tier. Passenger tier. It determined everything. Not just boarding. Rebooking priority when a flight cancelled. Whether the agent was authorized to offer a hotel voucher. How much flexibility you had. Pax tier.
You worked the gate.
Hilbert: Eighteen months. Regional carrier out of a mid-sized airport. Nineteen ninety-four, ninety-five. The system had a field called pax tier and we lived by it. The curtain between cabins is not the real marker. The real marker is the rebooking priority queue. Invisible to passengers. Enforced by us at the counter while smiling.
The class system is deepest exactly where the passenger can't see it.
Hilbert: Snowstorm night. Everything cancelled. I had a line of people at the counter. Family in economy. Two kids. I had to tell them the first class passengers would be rebooked first. The father said of course. That was worse than if he'd argued.
He'd internalized it.
Hilbert: He knew the rule without being told. That's a class system. You don't need a curtain. You need everyone to know the order.
The order was in the computer.
Hilbert: We had a laminated card from training. Pax tier reference. Listed the tiers in order. Top one had an asterisk. Never deny.
Never deny. That's the whole thing in two words.
Hilbert: I still have it. In a drawer. Never deny.
The card is the sumptuary law. The asterisk is the ermine.
Hilbert: The father said of course. I think about that more than the card.
The card tells you the rule. The father tells you the rule worked.
Hilbert: He wasn't angry. That's what got me. He expected it. He knew where he stood in the queue and he accepted it. The airline didn't have to explain anything.
The real class marker isn't the seat. It's the priority you don't see until something breaks.
Hilbert: The seat is the advertisement. The priority is the product.
The product is assignment. You're in a tier. The tier determines what happens to you when the system fails. The failure is when the class system becomes visible.
Hilbert: The father already knew his tier. That's why he said of course.
That's darker than the curtain.
Hilbert: The curtain is honest. The queue is the part nobody watches.
The queue is where the assignment happens. The curtain is just the set dressing.
Hilbert: Never deny. That was the whole training. Top tier gets what they want. Everyone else gets what's left.
The laminated card is the modern casta painting. A visual taxonomy of who gets rebooked first.
Hilbert: I don't know about paintings. I know the card listed six tiers and the top one had an asterisk.
Six tiers. More than varna.
Hilbert: More than the old four, yeah. And the bottom one, the field just said nonrev. Nonrevenue. That's the employee flying standby. They get nothing. They wait for everything.
Even the employees are in the hierarchy.
Hilbert: Especially the employees. We knew exactly where we stood. Below the paying tiers. The card made it official.
The sumptuary law always includes the people who enforce it.
Hilbert: We enforced it on ourselves. That's the part that stays with you.
The father said of course. The employee flies standby. The card says never deny. The whole system runs on people accepting their place in the queue.
Hilbert: The queue is invisible. That's the trick. The curtain you can see. The queue you can't. So nobody complains about the queue.
They complain about the legroom. The visible thing. Meanwhile the invisible thing determines whether they get home tonight or tomorrow.
Hilbert: The father didn't complain about anything. He just said of course.
There's a detail in what you said that I want to sit with. The laminated card listed six tiers. Varna has four plus the outside group. But the airline needed six. The modern system is more differentiated than the ancient one. It has more gradations.
Because the market wants finer sorting. The old systems were coarse. Four categories. Five. The airline found that six was the right number for its purposes. The logic of assignment didn't change. The resolution got higher.
Hilbert: The card was laminated. That's the part that gets me. Somebody in training thought this mattered enough to preserve. To make durable. The sumptuary law gets written on parchment. The pax tier card gets laminated. Same impulse.
The cutting room floor detail I keep thinking about is the casta paintings. They were commissioned by colonial elites and sometimes sent back to Spain as a way of showing the complexity of the social order in the colonies. A society painting its own hierarchy to make it legible to the metropole. That's the same impulse as the laminated pax tier card. Make the order visible to the people who run it.
The card outlived the job. That's the thing about these markers. They're durable. The sumptuary law gets repealed, the card stays in a drawer. The caste system gets constitutionally abolished, the jati keeps running the marriage market.
The open question is what happens as more of life moves into purchased tiers. Airlines, theme parks, subscription software, health care concierge services. Does the taboo erode, or does it just migrate to new vocabulary.
The Indian case suggests the vocabulary migrates. Caste didn't disappear under constitutional democracy. It became a legal category, a political identity, a basis for claims. The stratification persisted while the language around it modernized.
Which is an uncomfortable thought for anyone who assumes legal equality dissolves ascriptive class. It doesn't. It renegotiates it.
The airline case suggests the market does the same thing. It takes the old structure and sells it as a menu. The assignment persists. The framing changes.
The taboo was never about hierarchy. It was about honesty. We don't mind being sorted. We mind being told the sorting is assigned rather than chosen.
The places where the sorting is still visible, the boarding gate, the reservation quota, the marriage market, those are the places where the old machinery is still running, just with new labels.
I keep coming back to the father in the snowstorm. He said of course. Not because he'd read the card. Because he'd read the world. The card was just the confirmation.
The card is the explicit version of what everyone already knows. That's what makes it a sumptuary document. It doesn't create the order. It records it. Makes it legible. The legibility is the point.
The legibility is what we're not supposed to want. The whole meritocratic story depends on the categories staying soft. The moment you laminate the card, you've admitted the thing we're not supposed to say.
Hilbert: We laminated it because we needed it. The system broke down without it. Snowstorm night, six tiers, never deny. You can't run that on vibes.
The soft categories work for analysis. They don't work for allocation. The moment you have to allocate scarce resources, the categories have to get sharp. That's the difference Daniel was circling.
Description versus assignment. The description can stay fuzzy because it doesn't have to do anything. The assignment has to be sharp because it determines who gets the hotel voucher.
Hilbert: The sharpness is the uncomfortable part. The father didn't need the card. He already knew. The card was for us.
The card was for the people who had to enforce the order. The people being sorted didn't need the card. They'd been reading the order their whole lives.
That's the thing about caste. That's the thing about the Cagot. That's the thing about the airline. The people at the bottom don't need the documentation. They know.
Hilbert: The father said of course.
Yeah. That's the whole thing.
The documentation is for the people who might otherwise forget. Or pretend not to know. The card makes pretending impossible.
Daniel's question, why the back door exists, the answer is that the back door is the main door. The taboo is the back door. The open sorting is the thing that never stopped.
The taboo is a story we tell about the sorting. The sorting itself just keeps running, in the marriage market, in the reservation quota, in the pax tier field.
The laminated card is the story leaking. The moment the story breaks, the card is there, in a drawer, saying never deny.
Hilbert: I should probably throw it away.
No. Keep it. It's a primary source.
That's the thing about the markers. They outlive the system. The card is the casta painting of the regional airline. A document of a society trying to make its stratification legible.
Hilbert: I never thought of it as a document. I thought of it as a job aid.
The job aid is the document. The training card is the sumptuary law. The field in the computer is the enforcement mechanism. The father's resignation is the social reproduction.
The whole thing runs on the fact that nobody calls it class. They call it pax tier. They call it fare class. They call it boarding group. The vocabulary migrates. The allocation doesn't.
Which is the answer to Daniel's third question. How the old machinery looked. It looked like a laminated card. It looked like a casta painting. It looked like a sumptuary statute. It looked like a marriage rule. The machinery is always the same. A way of marking, a way of enforcing, a way of making the order legible.
The difference between that and the loose language of working class and middle class is that the loose language doesn't have a card. It doesn't have a field in a computer. It doesn't have a never deny asterisk. It's description, not assignment.
The description is what you say at a dinner party. The assignment is what happens when the snowstorm hits.
Hilbert: The father said of course.
Yeah. He knew the assignment.
The assignment is always there. The description is just the story we tell about it.
Thanks to Hilbert Flumingtop for producing, and for the laminated card I now cannot stop thinking about.
