Accumulation applied to politics. Power moves in a season, ideology in a generation, and culture is what both leave behind once they settle. Vietnam, France, the United States and Australia, read by the thickness of their sediment.

From a quiet place on the far side of the Pacific, the second Trump presidency is best watched with the sound turned down. Donald Trump has no settled doctrine, no cathedral of ideas he is building toward; his positions on trade, on Russia, on his own party's orthodoxies move with the week. What you see instead is a pure student of power — its acquisition, its display, its uses against enemies and for friends — draped in a culture heartfelt but seemingly manipulated for his purposes, the flag-and-faith iconography of an older America worn like a borrowed coat. He is, precisely, a Machiavellian: heavy on power, light on ideology, and reliant for legitimacy on a cultural inheritance that is moving beneath his feet. Many stateside friends of mine love him, and call him “My President”, and others are either full of fear and loathing or cuckolded with embarrassment. The cultural divide is sharp, and I’ll come back to that.

That single figure contains the whole argument I want to make. Political order is not one thing but three, moving at three different speeds. There is power — the hard architecture of institutions, coercion, money and command, the layer that can change in a season. There is ideology — the story a society tells about why those with power deserve it and why the rest should comply. And there is culture — the slow accumulation of everything a people has lived through, settled so deep that it is no longer argued but simply assumed. Most of our political commentary treats these as rival explanations: the institutionalist sees only power, the theorist only ideology, the culture critic only identity. Each is holding one limb of the animal.

The reframe I would urge is this. Culture is not a third thing standing beside the other two. It is mostly the other two — power and ideology accumulated over generations and set hard, the way sediment is only the silt from yesteryear's flood waters deposited over time, slowly compressing to a firmer sedimentary structure. What a people will accept, resist or demand today is the settled residue of the power arrangements and the justifying stories it absorbed long before anyone now living was old enough to question them. This is why culture is the slowest layer to move, and why, when it finally does move, power and ideology have no choice but to follow.

None of this is a model — no equations, no machinery, nothing that claims to predict an election. It is a way of seeing: a lens that treats a political system as a living thing with a fast surface and a deep memory. So let me use it, and then name what would count against it.

Begin with the fast layer. Machiavelli, writing in Florence in the 1510s after watching the Medici expelled and restored and a republic rise and fall inside a decade, was the first to study power stripped of the stories we drape over it — how it is taken, how it is held, how it is lost. He was not immoral; he was simply clear about which layer he was examining. His prince who knows when to be the lion and when to be the fox is a description of power operating without the cushion of settled legitimacy.

Ideology is the layer that converts raw power into authority. Its function is to make command feel legitimate, so that compliance becomes internal rather than enforced — cheaper than any army, more durable than any surveillance. Divine right, the mandate of heaven, popular sovereignty, the vanguard of the proletariat, liberal democracy: each is a story about why the powerful are entitled and the governed are doing right to obey. An ideology that sinks deep enough stops being a belief anyone defends and becomes part of the furniture. That is the moment it passes into culture.

And culture, the deepest layer, is where beliefs go once they have stopped being argued. Antonio Gramsci, writing from one of Mussolini's prisons in the 1930s and trying to understand why the workers were not revolting on schedule, gave this its sharpest name: hegemony, the condition in which a ruling arrangement has so thoroughly seeded the common sense of a society that its dominance feels natural, inevitable, in everyone's interest. Gramsci saw that the real battleground was never the parliament or the factory floor but the cultural layer beneath both — the stories a society tells about itself, the options that feel thinkable. What he lacked was a mechanism. The mechanism is accumulation: culture is what a people has integrated so early and so deeply that it now runs below the threshold of belief.

Three cases show the layers in alignment, in contradiction and in fracture; two more, briefly, show what happens where the sediment is thin or imported.

Vietnam, where I lived for twenty-five years, is the case of a thick and coherent culture, and it is routinely misread. The stability of the one-party state is credited to the discipline of the Communist Party, and that is not wrong, only shallow. The deeper source is a cultural grammar of governance — hierarchy, collective orientation, the subordination of private interest to communal order — that Vietnam absorbed and adapted across centuries of engagement with and resistance to China, and that predates the Party by a thousand years. A society that survived Chinese domination for a millennium, French rule for eighty years, American intervention for twenty and Khmer Rouge raids on its southern border did not learn its premium on unity from a politburo. The Party did not manufacture that cohesion; it inherited it, and has deployed it with considerable skill. To Lam, who now stakes his authority on double-digit growth and a severe anti-corruption drive, governs a system whose real reservoir of legitimacy is not economic performance but this cultural depth — and its long-run threat is not dissidence but the slow thinning of that fabric as a younger, more connected generation accumulates different experiences. Thick-and-coherent culture stabilises a centralised system precisely by making its authority feel less like imposition than like the order of things.

France is the instructive complication: a thick culture that is nonetheless chronically brittle. By every surface measure France should be stable — a deep historical identity, a powerful republican tradition, a centralised state, fierce attachment to language and civic symbol. Yet it is a country of periodic revolution, recurring paralysis and constitutional rupture. The reason is that its cultural sediment is not merely thick; it is internally contradictory. The republican insistence on a single, secular citizenship sits in permanent tension with the country's Catholic inheritance, its regional identities and, increasingly, its large Muslim population; the left and right carry mutually exclusive accounts of the Revolution itself. When stress arrives it does not disperse across a flexible fabric. It runs along cracks that were already there.

France has staged this before, at the origin. Robespierre's Republic of Virtue was an ideological programme of real coherence and moral ambition, driven against a culture that was Catholic, regional, hierarchical and saturated with centuries of accumulated responses to authority, which the ideology could not absorb. The power layer had no error-correction; the ideology had no capacity to check itself against cultural reality; the result was the Terror, a catastrophic oscillation before the system found a new equilibrium. Napoleon was not the betrayal of the Revolution but the mechanism by which its durable achievements — equality before the law, careers open to talent, the rational state — were extracted from the wreck and made portable, carried across Europe in the Napoleonic Code alongside the muskets. The pattern still runs. Since the snap election of 2024 left the National Assembly with no majority, France has churned through prime ministers — Barnier, Bayrou, Lecornu resigning and being reappointed inside a single week — and adopted a 2026 budget only in February, and only after two no-confidence votes had failed. Thick-but-contradictory culture does not absorb shock. It amplifies it.

The United States is the fracture case, and the one whose trouble is most often misdiagnosed. Americans analyse themselves in the vocabulary of ideology — liberal against conservative, progressive against populist — but the deeper condition is cultural fragmentation. The American substrate has split into incompatible layers: an individualist inheritance, a religious pluralism, an unresolved racial history, and now a digital ecosystem engineered to reward outrage and punish complexity. Power is dispersed and competitive, which in a coherent culture is a stabiliser and in a fractured one is an accelerant, because every institution becomes a prize to be captured rather than a boundary to be respected. Ideology has become a proxy for cultural identity, and once a political disagreement has crossed into a fight about who you are, it is no longer amenable to the ordinary settlements of politics — the split difference, the deferred question, the loss survived. When good friends cannot discuss the issues anymore, when the deep rifts extend across the family table, and outrageous responses are deemed necessary to make up for perceived dubious decisions from the other side, well it reminds me of what happened in families during the Vietnam war.

Gramsci's hegemony describes what the United States has lost: the shared common sense that once let very different Americans agree on what the argument was even about. Watch the layers grind. The courts, which are supposed to be the slow boundary on the fast layer, have become a front in the war: in February 2026 the Supreme Court struck down the emergency-powers tariffs central to its economic programme, and by mid-year the White House was racing to reconstruct the tariff wall through other statutory doors — power tested against power, with the cultural agreement that once made such tests feel routine largely gone. What deepens the American case beyond France's is that the fracture is actively farmed: a media and platform economy that profits from engagement widens the cracks rather than letting them close, turning the cultural layer from a healthy polity's shock absorber into its shock generator. This is the sharpest danger: a fractured culture destabilises whatever institutions sit on top of it, democratic or otherwise, and no redesign of the institutions alone repairs it.

Now the payoff, closest to home for an Australian reader. Australia is the case of a thin culture, and its thinness is not a poverty but an achievement. The political order rests on a low-symbolic, easy-going, pragmatic fabric that keeps the emotional stakes of disagreement low. Power is dispersed — federation, courts, a robust press, compulsory voting that drags every contest back toward the centre — and the prevailing ideology is procedural rather than messianic: Australians expect competence and fair dealing, not national destiny. This is why the country absorbs immigration, economic shock and social change with turbulence that would tear a thicker culture apart, and why the 2025 election could return the Albanese government in a landslide while the opposition simply collapsed. The 2023 Voice referendum is the same lesson from the other side: a hard question was asked, the country answered no, and the sky did not fall, because the thin fabric had room to absorb both the asking and the answer.

The risk peculiar to a thin culture is not that it will fracture but that, having little thickness of its own, it will import thickness from abroad — and Australia is being offered it from two directions at once. From the United Kingdom and Europe comes a social-democratic reflex that would fill the thinness with programme and entitlement; from the United States comes a culture-war framing that would fill it with borrowed grievances, imported identities and enemies that are not ours. The sharpest version of the point is this: the Australian leaders who succeed are the ones who read the local cultural substrate, and the ones who fail parrot American culture-war scripts into a country that has no native quarrel to match them. The task is to absorb neither wholesale — to resist the temptation to thicken a culture whose very thinness is the thing worth keeping.

There is a newer channel for imported sediment, and it arrives through the chat window. A large language model is trained on a corpus, and a corpus is a culture’s accumulated deposit: its arguments, its assumptions, what it treats as settled. We should expect an American model and a Chinese model to differ, not in their grammar but in their common sense. Beijing already sees it that way. In September 2026 Chen Yixin, head of China’s Ministry of State Security, warned that artificial intelligence could threaten the Party’s hold on power, named American models among the new dangers, and called for tighter Party control. Beijing does not treat a model as neutral, and neither should we. A thin culture that takes its models from abroad imports thickness by the query. There is a case for an Australian one.

Two shorter cases show the argument's edges. India should not, on this logic, hold together at all: twenty-two official languages, every major religion, caste, region and the deep scarring of colonial disruption. Yet its democracy has persisted, imperfectly, for more than seventy years — because its fabric is fractured at the national level but often thick locally, and because the Nehruvian settlement of secular federalism was a deliberate ideological architecture built to hold a plural society together. That settlement is now under strain, as a Hindu-nationalist project seeks to impose a single, thicker national identity onto a stubbornly plural country; Modi, governing since 2024 through coalition after losing his majority, has since consolidated through state-election victories. And here is the deeper worry: the Indian tradition may, at the crunch, favour the maharaja who delivers over the secular democrat who merely presides — and that preference, not any constitutional clause, is the live risk under the current dispensation.

Africa carries the warning in its harshest form. Across the post-colonial world, Western constitutional forms were transplanted onto cultural sediment that was thin, fractured, or shaped by entirely different assumptions about authority and belonging. The written constitution is only the deposit; the living institution is the shared understanding among the people inside it, and where that understanding is absent the forms hollow out. South Africa is the test now being run in real time: the African National Congress lost its majority in 2024 and governs in an uneasy unity coalition with the Democratic Alliance, and South African commentators themselves are drawing the Zimbabwe comparison openly — a liberation movement that captures the state, hollows the institutions from within, and leaves the constitutional shell standing over a one-party reality. Thin or fractured sediment cannot hold a heavy constitution up on its own.

Which brings me to the honest limit of any lens like this, and the objection it must answer. A framework that files every country under thick, thin, contradictory or fractured risks explaining everything and testing nothing; give me an outcome and I can find you the cultural reading that fits it after the fact. That objection is fair, and the discipline it demands is to say in advance what would count against the view. If a thick-and-coherent culture collapsed for reasons that had nothing to do with any cultural shift; if a country repeatedly re-engineered its institutions and its culture obligingly followed within a few years rather than a few generations— then the lens would be wrong, and should be dropped. So far, the opposite keeps happening: institutional change outruns cultural change, and the gap between them is where the trouble lives. This is the old quarrel between Burke, who insisted that a civilisation's accumulated arrangements carry a wisdom no reformer can replicate overnight, and Paine, who insisted that accumulation can harden injustice as easily as wisdom and must be open to rational repair. Both were right, and the tension between them is not a problem to be solved but the working mechanism of a healthy polity: a system that can only preserve drifts from reality, and a system that can only revise loses the inherited forms that make common life possible.

So to the Australian wager, which is finally a matter of temperament as much as analysis. A thin culture is not an empty one. It is the residue of freedom — of a people who have not been made to carry heavy inherited quarrels, and whose lightness is the accumulated evidence of not having needed them. Tony Abbott's recent history of the country, Australia: A History, makes the affirmative case plainly: for all the arguments over it, this has been a strikingly successful liberal project, an ancient land that became a great democracy. Menzies may have had a conservative character, but he governed with a liberal tolerance and a fiscal responsibility that might well be attractive today. Having spent much of my working life abroad, I have come home to the same conviction — that whatever the quarrels between our competing political interests, the result has been exceptional, and worth defending as such. The standing temptation of every leader is to treat the thinness as a vacancy and rush to fill it, with a national story, a redemptive programme, an imported culture war. The impulse is not ignoble — a thin culture can feel like a society with too little holding it together — but the deeper duty runs the other way: to protect the thinness, to govern lightly, and to resist the borrowed thickness pressing in from both oceans, trusting that a fabric strong enough to give without breaking is worth more than one heavy enough to shatter. Perhaps the least acute observation — and here I am deliberately echoing John Howard, who built a career on the claim that what unites Australians outweighs what divides them — is that a leader aligned with the values the sediment already carries, a fair go, tolerance for others, some fiscal discipline and the management of vested interests, stands on far surer ground than one reaching for something the sediment will not bear. Immigration is as much a matter of composition as degree. The intake has climbed — roughly 100,000 a year under Howard, 180,000 under Abbott, 240,000 under Morrison and some 400,000 under Albanese, with One Nation now proposing 130,000 — yet fewer than 5,000 of that number are construction workers. We import the demand for housing without the hands to build the supply; if housing cost is really a construction-supply problem, that makes it worse, not better, and only the vested interests on both sides explain why we so rarely say so.

Culture is the sediment beneath politics, and most of what looks like a crisis of institutions or ideas is really the slow ground shifting underneath. The wisest thing a country can do is to know its own sediment — how thick, how coherent, where the fault lines run — and to govern as if the ground, not the noise on its surface, were the thing that finally decides.

Note on method. The ideas here are mine, and have been the subject of a human quest you can follow at www.integraloflife.com. As an engineer I am comfortable having them written with an LLM in support, as much as you presumably are about the software that helped design the aircraft you fly in.
