The Economics of Power: Why the West’s Greatest Challenge Begins at Home

For most of the modern age, military power, industrial strength, finance, energy and technology reinforced one another. Today they are beginning to pull in different directions. The argument over American decline is therefore being conducted in the wrong language. The deeper question is whether the economic system beneath Western power can still support the strategic system built upon it.

In the desert outside Las Vegas, the future arrives as a low mechanical hum. Inside immense halls, racks of processors consume electricity, water and capital at a rate once associated with heavy industry. Far away, over battlefields in Europe and West Asia, small drones rise from improvised launch sites carrying cameras, explosives and components available through commercial supply chains. In Washington, Congress authorises another defence budget while the Treasury prepares to borrow the money required to finance it. In shipyards along the Chinese coast, vessels take shape beneath cranes moving with the rhythm of an industrial economy.

These events are usually reported as separate stories.

Artificial intelligence belongs to technology. Drones belong to war. Public debt belongs to economics. Shipbuilding belongs to industry. Energy belongs to climate and commodities. China belongs to geopolitics.

But the divisions are becoming artificial. The same electricity grid that must supply homes and factories is now being asked to power the data centres on which the next generation of artificial intelligence depends. The same semiconductor industry that produces civilian electronics supplies military guidance, communications and surveillance. The same public balance sheet that finances pensions and healthcare must also support weapons, industrial subsidies and rising interest payments. The same global supply chains built for efficiency are being reorganised for security.

Beneath the headlines, a single machinery is coming into view.

The moral inheritance of power

America approaches the end of its first 250 years with unmatched wealth, global military reach and a national story built around liberty. It also carries a history of slavery, continental conquest, racial hierarchy and repeated warfare abroad. Those facts have always existed beside the republick ideals. What has changed is the declining ability of the national myth to reconcile them.

The old answer was that America possessed within itself the means of correction. Its crimes were grave, but its constitutional promises were larger. The country that tolerated segregation could produce a civil rights movement. The country that concentrated wealth could build public universities, social insurance and the infrastructure of a mass middle class. The good, in Bill Clinton formulation, might eventually repair the bad.

That confidence has thinned. Historical scholarship has deepened the record of dispossession and coercion, while politics has moved in the opposite direction, towards a more defensive nationalism. One side treats acknowledgment as an attack on the nation. The other too often substitutes ceremony for repair. The result is not reconciliation but distance. The official language grows more radiant as the material landscape grows harder to explain.

This matters because power is never only a balance sheet. A state can demand sacrifice abroad only while enough of its population believes that the state represents something worth sacrificing for. The United States once possessed an unusually strong combination of material abundance and political belief. It could build weapons on an industrial scale because it also built houses, roads, universities and secure employment. The arsenal and the social order grew together.

The weakening of that compact is not itself the cause of American decline. It is the moral atmosphere in which the economic causes operate.

When power became a financial asset

The United States did not cease to produce. It became extraordinarily productive in new ways. It created the worlds deepest capital markets, its most valuable technology companies and an innovation system capable of reorganising whole industries. Yet the rewards of that system moved steadily towards owners of assets, intellectual property and financial claims.

Factories became balance sheet decisions. Supply chains were dispersed across borders. Companies discovered that returns could often be increased more reliably by controlling platforms, brands, patents and finance than by maintaining redundant domestic capacity. The system was efficient in peace because it removed spare capacity, shortened inventories and placed production wherever costs were lowest.

War asks different questions.

It asks how many missiles can be produced after the stockpile has been fired. It asks how quickly a damaged ship can return to sea, where the replacement radar will come from, whether the machine tools exist and whether the workforce still possesses the required skills. It asks whether a country can continue producing after transport routes are disrupted and suppliers become adversaries.

The lesson emerging from Ukraine, and more recently from the conflict with Iran, is that modern war remains industrial. Software can improve targeting. Satellites can expose movement. Artificial intelligence can shorten the time between detection and attack. None of these abolishes the need for explosives, motors, launchers, repair facilities, fuel and people.

Money can be created in an afternoon. A missile production line cannot.

The point is not that the American military is weak. It remains capable of projecting destruction across distances no other state can match. Nor is every expensive weapons programme a failure. The F 35 is a formidable aircraft, supported by a network of sensors, allies and logistics that no rival has reproduced in full.

But cost has become a strategic fact. The Government Accountability Office says the projected lifetime sustainment bill for the American F 35 fleet stands at about $1.6 trillion. Availability has repeatedly fallen below service goals. More broadly, American defence analysis now speaks openly of insufficient magazine depth, long replenishment times and an industrial base that may not sustain an extended conflict with a peer adversary.

The United States spent decades designing a force for rapid technological dominance. Its potential adversaries studied the design and searched for the price points at which it could be strained. A cheap drone does not need to equal a sophisticated interceptor. It needs only to force the interceptor to be launched. A missile does not need to sink an aircraft carrier to alter its operations. It may be enough to push the ship farther from the coast, reducing the range and tempo of the aircraft it carries.

The contest is increasingly between exquisite capability and production at scale.

The factory behind the battlefield

China changes this arithmetic not because it has already displaced American power, but because it sits at the centre of a manufacturing region that has acquired extraordinary breadth. Asia and Oceania produced more than 57 per cent of global manufacturing value added in 2024, according to the United Nations Industrial Development Organization. The region also accounted for nearly half of world exports of manufactured goods.

This is not simply a matter of wages or volume. It is an ecosystem. Batteries, electric motors, commercial drones, electronics, telecommunications equipment, machine tools, solar panels, ships and processed minerals exist within overlapping industrial networks. Civilian scale creates military options.

China can be challenged in individual technologies. It remains dependent in some areas. Its economy carries large debts, a property overhang, weak household demand and an ageing population. None of this removes the industrial fact. A country able to manufacture consumer goods in immense quantities can redirect portions of that capacity when strategy demands it.

Washington has begun to answer with industrial policy. Semiconductor subsidies, battery plants, mineral agreements, shipyard investment and defence production contracts all recognise that markets optimised for quarterly returns will not necessarily provide strategic resilience. The United States is also drawing more heavily upon Japanese and South Korean shipbuilding and manufacturing expertise.

Here the system encounters another contradiction. Japan and South Korea are security partners of the United States, but their industries are deeply connected to China. Washington wants them as components of a strategic coalition against the country around which much of their regional trade is organised. Security points east across the Pacific. Economic gravity points west towards the Asian mainland.

Governments can resist economic gravity. Europe did so when it severed much of its energy relationship with Russia. But gravity does not disappear merely because policy changes direction. It reappears as cost.

Energy returns to the centre

For a generation, the digital economy encouraged the illusion that advanced power was becoming weightless. The most valuable companies appeared to live in code, networks and intellectual property. Artificial intelligence has exposed the physical structure beneath the cloud.

The International Energy Agency expects global data centre electricity consumption to roughly double by 2030. In the United States, data centres are projected to account for about half the growth in electricity demand over the next five years. The new industrial centres require power stations, transmission lines, cooling systems, transformers, water and land.

AI is therefore not merely a technology story. It is an energy story, a construction story, a capital allocation story and, increasingly, a national security story.

The excitement may also contain a financial danger. The useful distinction is between the trajectory of a technology and the price placed upon it. Electricity transformed the world after the speculative excesses surrounding electrification. The internet continued changing commerce after the dot com crash destroyed many companies that had correctly recognised its importance. A technology can be revolutionary while its securities are overvalued.

The present investment race contains the familiar ingredients. Companies fear that insufficient spending will leave them behind. Investors fear missing the dominant platform. Enormous valuations create collateral, collateral supports borrowing and borrowing feeds further investment. The process can continue long after sceptics first identify a bubble.

If it reverses, the technology will not vanish. Data centres will remain. Models will improve. The infrastructure will find uses. But asset prices, employment and public revenues may move on a different timetable.

That matters because the United States is now asking the same capital system to finance several historic projects simultaneously: the AI buildout, the energy grid required to support it, the reindustrialisation of strategic sectors and a military establishment preparing for prolonged competition across several regions.

The debt beneath the flag

The United States can finance more than most countries because the dollar remains the principal reserve currency and Treasury securities remain central to global finance. It does not depend on China or Japan alone to purchase its debt. American banks, pension funds, insurers, households and global investors form a vast market.

That privilege is sometimes mistaken for the abolition of limits.

The Congressional Budget Office projects net federal interest costs above $1 trillion in 2026. It expects the deficit to remain close to $1.9 trillion, with rising interest costs accounting for much of the longer term deterioration. The International Monetary Fund places American general government debt at roughly 126 per cent of gross domestic product this year.

None of these numbers predicts collapse. A sovereign state borrowing in its own currency is not a household. The American economy remains large, innovative and capable of attracting capital during crises. Debt becomes dangerous less as a single threshold than as a narrowing of choice.

Interest must be paid before a new bridge is built. Defence contracts compete with energy infrastructure. Semiconductor subsidies compete with healthcare. Tax reductions compete with every programme the state wishes to preserve. Each decision remains politically possible. Fewer remain possible together.

Dalio describes this as part of a long cycle in which debt, wealth inequality, domestic conflict and external rivalry intensify at roughly the same historical moment. His cycle should not be treated as a clock. Empires do not expire after a fixed number of years. But the relationships he identifies are visible.

When asset ownership becomes concentrated, technological progress can enrich the economy while leaving much of the population feeling poorer. When governments are heavily indebted, each downturn becomes a distributive struggle. When political coalitions can no longer agree on who should pay, foreign policy promises become easier to make than domestic compromises.

The military budget then serves several purposes at once. It funds deterrence and war. It sustains industrial employment. It directs public money towards private contractors. It supports alliances. It signals national resolve. In weakened industrial regions, it can also become one of the few politically acceptable forms of state led economic policy.

Europe is already confronting a version of this problem. Higher energy costs, Chinese competition, ageing populations, weak growth and demands for greater defence expenditure are converging. Germany remains a formidable industrial economy, but the model built on export manufacturing and comparatively inexpensive energy has been damaged. Britain faces its own mixture of low investment, weak productivity and rising fiscal claims.

Europe is not collapsing. It is discovering how expensive strategic independence becomes after industrial capacity, energy systems and military protection have been treated as separate questions.

The price of refusing limits

The traditional account of imperial overstretch begins with foreign commitments. A great power acquires obligations faster than it acquires resources. Garrisons spread. Wars multiply. The centre weakens under the weight of the perimeter.

The present system is more intricate. Military commitments are not simply draining an otherwise healthy economy. They are revealing tensions already embedded within it.

A financialised economy produced extraordinary technological firms but weakened parts of the industrial commons. A globalised economy reduced costs but created strategic dependence. A professional military reduced the domestic political cost of war but separated conflict from most citizens’ daily lives. Cheap energy supported growth while concealing vulnerability. The dollar financed global reach while allowing deficits to accumulate.

Every successful arrangement carried within it the conditions of the present difficulty.

This is why the debate cannot be settled by comparing defence budgets or counting ships. American military expenditure remains immense, but expenditure is an input, not an outcome. China’s industrial scale is formidable, but factories do not automatically produce alliances, combat experience or political trust. Russia and Iran can impose costs, but they also face deep limits of their own.

The question is which system can convert its resources into durable power without damaging the society from which those resources are drawn.

America retains advantages that earlier declining powers would have envied: continental scale, food and energy resources, favourable geography, leading universities, deep capital markets, immigration, technological invention and a network of allies. Decline is not a verdict delivered by history. It is a relationship between what a state attempts and what its institutions can sustain.

The harder choice lies between adaptation and denial.

Adaptation would require deciding which commitments are essential, rebuilding productive capacity without turning every industry into a permanent ward of the state, reforming taxation and expenditure, modernising the grid, widening access to the gains from technology and accepting that other powers will possess interests Washington cannot simply overrule.

Denial is easier. It requires another budget, another sanction, another weapons system, another declaration that the existing order remains unchanged.

For a time, both paths can look remarkably similar. The ships remain at sea. Markets open each morning. Data centres rise from cleared land. Factories receive new orders. Governments promise renewal.

Only later does it become clear whether the machinery was being rebuilt, or merely driven harder.
