Long-term indicator · Income concentration

We have been here before — and last time it ended in 1929.

United States · share of national income taken by the top 1% (%)

The richest 1% of Americans now capture about a fifth of all income — nearly the Gilded-Age record.

The top 1% share sits near 21% (World Inequality Database), closing on its 1928 peak of 23.9% (Piketty & Saez). The top 10% take about half of all income, and wealth is more concentrated still. History's warning is blunt: societies that let a tiny elite capture this much have rarely held together for long.

⚖️ What this indicator measures

Not envy. A load-bearing variable.

BEAVER.WATCH does not track inequality as a moral scorecard. It tracks it because, in Peter Turchin's structural-demographic model, extreme income concentration is one of the most reliable load-bearing warnings of coming instability. His mechanism: a "wealth pump" moves income upward, the many are squeezed (popular immiseration), and the elite overproduces — more rich, credentialed contenders than there are seats of power — until some of them turn against the system.

One honest caveat: the exact magnitude is debated — some economists (Auten & Splinter) argue the rise is smaller once taxes and transfers are counted. But every major series agrees on the shape: a deep U, and we are climbing its far wall. The level is not the alarm. The direction is.

📚 The oldest pattern in politics

Three times a few captured almost everything — and then the roof came down.

Antiquity · Roman Republic

🏛️ The Gracchi and the latifundia

133 → 27 BC · a century of collapse

Imagine Italy in 133 BC. Conquest has flooded Rome with slaves and plunder; senatorial families swallow the countryside into vast estates — latifundia — while soldier-farmers return from war to find their land gone. Wealth locks in power: the share of consuls born to consuls climbs from 45% to 64% (Turchin & Nefedov, Secular Cycles) — elite overproduction in a single phrase. The Gracchi brothers propose land reform; the Senate has them killed (133 and 121 BC). Political murder, once unthinkable, becomes routine. A century of civil war follows, and the Republic dies into empire.

⚡ The wow effect

Rome was not conquered from outside. Its Republic died when a narrow elite captured the land, then the state — and chose murder over reform. Inequality wrote the first act of its fall.

18th century · France

🇫🇷 The Ancien Régime cracks

1789 · a summer that ended a world

Imagine France in the 1780s. A tiny nobility and clergy own much of the land and are largely exempt from tax, while the Third Estate — 98% of the nation — carries the fiscal weight of a bankrupt crown. Harvests fail, bread prices spike, the state cannot pay its debts. The gap between splendour and hunger becomes unbearable. In 1789 the structure gives way all at once: the Bastille, the abolition of privilege, and then the Terror. One of Europe's oldest monarchies is gone in a few years.

⚡ The wow effect

The Revolution did not begin with ideas alone. It began with a distribution of wealth and tax so lopsided that the majority had nothing left to lose. Extreme inequality is combustible — it only needs a spark.

Then and now · United States

🇺🇸 The two Gilded Ages

1928 → today · one full U-curve

Imagine America in 1928. The top 1% take 23.9% of all income — a Gilded-Age summit. Within a year the market collapses; the 1930s and 40s bring the New Deal, mass unions, a top tax rate above 90% and war — the Great Compression drives the top share down to roughly 10% by the 1970s. Then, from 1980, the pump reverses: deregulation and tax cuts send it climbing all the way back to ~21% today. Turchin, modelling these cycles, published a warning in 2010 that US instability would peak around 2020. The 2020s have not disappointed him.

⚡ The wow effect

America already ran this experiment once. It climbed to a Gilded-Age peak, crashed, and spent forty years building a broad middle class — then dismantled it in forty more. We are now standing almost exactly where 1928 stood.

Rome, France, America: the substances differ, the pattern is one. When a few capture almost everything, the many stop believing in the rules — and the rules are what hold a society together. That is why the Beaver watches the top 1%.

🧭 The structural reading

How a distribution becomes a destabiliser

01 · SOCIOLOGICAL — popular immiseration

The squeezed 90%

As the top pulls away, the bottom 90%'s share of income and wealth shrinks and mobility stalls — the felt sense that the game is rigged. That perception is the raw fuel of the deaths-of-despair cluster on one side and of populist anger on the other. Inequality is not an isolated number; it sits under half the other indicators on this board.

02 · GEOPOLITICAL — internal · elite overproduction & capture

Too many contenders, too few seats

Turchin's sharpest mechanism: concentrated wealth funds a glut of would-be elites competing for a fixed number of top positions. The losers — credentialed, ambitious, thwarted — become counter-elites who attack the system itself. Meanwhile money buys policy (the "wealth pump" locking in), eroding trust that the state serves the many. This is the internal engine of polarisation and institutional decay.

03 · GEOPOLITICAL — external · a house divided

Cohesion is a strategic asset

A great power riven by inequality fields a divided society against united rivals — weaker consensus for long-term strategy, more vulnerable to foreign wedge campaigns, and, historically, prone to the internal convulsions (Rome, France, the 1930s) that redraw the map. National power rests on legitimacy, and legitimacy erodes when the many conclude the system exists for the few. Inequality is a national-security variable, not only an economic one.

Reversible

the U-curve proves it

The most hopeful fact on this page is the left side of the U. Between the 1930s and 1970s, the US cut top income shares by more than half — through progressive taxation, mass unionisation and broad-based growth — and built the largest middle class in history. It was policy, not fate. The pump can be run in reverse. America has done it before.

We have been here before — and last time it ended in 1929.

The U-curve: down for fifty years, up for forty.
