Capitalism ran on a simple loop: More people → more workers → more wages → more consumers → more profits → more investment → more jobs. GDP growth was population + productivity.
That loop is stalling: · Population: Working-age cohort globally peaks ∼2025. Japan, China, Korea, and Europe ex-immigration are already shrinking. · Jobs: Goldman Sachs sees 300M jobs exposed to AI automation by 2030. Tesla, Figure, and Agility have humanoids piloting warehouse/factory work at $16-$30/hr all-in cost, falling ∼10% per year.
For the first time since the Black Death, we may have fewer workers and less need for them. The loop reverses: Fewer people + fewer jobs needed = who earns the income to buy what the robots make?
Yes, Some Corporates Can Still Profit for 20 Years
Degrowth ≠ no profits. It means profits concentrate. Japan 1990-2025 proves it: Company Home Pop 1990-2020 EPS CAGR How Keyence -0.1% CAGR ~16% Sold factory sensors globally. 80% gross margin, no factories Toyota -0.1% CAGR ~8% Exported 80% of cars. Hybrid tech = pricing power Novo Nordisk +0.4% CAGR ~18% Diabetes drugs for aging world. 90% revenue outside Denmark The degrowth profit formula: EPS growth = Pricing power × Productivity × Global share – Labour cost
If you raise prices 3%/yr, cut headcount 2%/yr via AI/robots, and sell to India/Africa where population still grows, you can compound 10-15% while home GDP = 0%.
But if only 20% of firms do that and employ 20% of workers, who buys the output?
Who Will Buy When the Jobs Die? — With AI & Humanoid Robots
There are only 5 sources of buying power. In degrowth
automation, 3 weaken and 2 must expand, or demand collapses.
A. The State Becomes Buyer of Last Resort When households can’t earn enough, governments run deficits and buy directly or via transfers. Japan: debt 60%→260% of GDP since 1990 to fund pensions, healthcare, public works. That spending is GDP.
AI/robot twist: Governments will be the biggest buyer of elder-care humanoids, AI tutors, and infrastructure bots. Private jobs die, but public spending creates demand for robot fleets. Funded by taxes on robot owners.
Limit: Works only if you can print your currency. World Bank/IMF loans in USD can’t be inflated away.
B. Retirees Spend Down Assets Aging societies are asset-rich: Japan households hold 2000 trillion yen, 3x GDP. US Boomers hold $80T. Retirees sell assets and buy services: healthcare, leisure, and now humanoid companions.
AI/robot twist: A humanoid elder-carer at $20k/yr vs human at $60k/yr is viable by 2028. Retiree dis-saving becomes revenue for robot firms.
Limit: Once assets are spent, demand falls. Dis-saving also pushes real rates up unless central banks suppress them.
C. Foreigners in Growing Populations Germany/Japan model: Export 5-8% of GDP yearly. Sell cars, robots, drugs to India, Nigeria, Indonesia.
AI/robot twist: Humanoids make re-shoring cheap. 10 engineers + 200 bots can run a factory. “Local costs, global revenue” accelerates.
Limit: Not everyone can run a surplus. If all aging countries export to India, India tariffs it. Currency wars follow.
D. High-Skill Workers Who Manage the Machines AI kills mid-skill jobs but raises pay for those who direct machines. Japan 1995-2020: total jobs -10%, IT jobs +40%, healthcare +60%. One human + 10 bots can run a restaurant. That human earns 10x.
Inequality rises, but consumption doesn’t zero out.
E. Capital Owners via Dividends/Buybacks If firms need fewer workers, profit share of GDP rises. US corporate profit/GDP: 5%→12% since 1990. Owners spend some.
Limit: Top 10% own 89% of US stocks. Their marginal propensity to consume is low. You can’t sell 10M cars to 1M billionaires.
Bottom line: Buyers = state + retirees + foreigners + high-skill workers + capital owners. If they don’t add up to output, you get deflation until capacity closes.
Why Humanoid Robots Make This Different From Past Automation
Tractors and Excel created jobs elsewhere. Humanoids + AI may not, because:
1. Generality: A bot can be reprogrammed overnight: warehouse → nurse → barista. Past machines did one task. 2. Cost curve: Target <$20k per bot = $1/hr capex. Humans cost $25-$40/hr. Cross-over is 2026-2030 for many jobs. 3. Scale speed: No sleep, no visas. Copy-paste software.
Labour shortage flips to labour glut in <10 years in rich countries. The “who buys” question arrives before pensions adjust.
How Do Countries Repay World Bank/IMF Loans When the Tax Base Shrinks?
External USD debt has only 4 exits:
1. Export surplus: Earn USD selling robots/drugs/IP. Needs world-beating firms. 2. Asset sales/FDI: Sell ports, land, companies for USD. Political backlash. 3. Austerity: Cut spending until imports < exports. Greece 2010-2018. Young emigrate. “Few people take responsibility” because others left. 4. Restructure/default: Haircut or forgiveness. HIPC wiped $76B for 37 nations.
Why few end up responsible: In degrowth, tax base narrows. Italy: 13% of taxpayers pay 60% of income tax. If top 10% + corporates pay, and they leave, debt is unpayable. IMF programs demand export growth + broader tax base for this reason.
Three Futures Path Who Buys Debt Politics 1. Techno-Abundance: State taxes robots/capital, funds UBI/services. Retirees spend. Inflated away slowly Stable if redistribution accepted 2. Neo-Feudalism: Only capital owners + exporters. Domestic demand dies Defaults/austerity Unstable, emigration, unrest 3. Managed Degrowth: Shorter work week, wealth caps, public AI. Less consumption needed Jubilee/restructure Needs values shift Japan/EU = Path 1 so far. Greece = Path 2 briefly. No one has done Path 3.
Can Corporates Profit for 20 Years in Global Degrowth? Yes, If…
Sell to aging: Drugs, automation, care.
Sell abroad: >50% revenue from growing countries.
Need few workers: Software margins, robot factories.
Return cash: Buybacks so EPS grows as shares shrink.
State recycles profits: Taxes fund customers.
Most firms fail #2-#5. They shrink or die. That’s why index returns are flat in degrowth, but 15-20% of stocks compound. Dispersion, not a bull market.
The Uncomfortable Answer
Production = Income = Expenditure. If machines produce and owners get the income, humans need a claim on that income to create expenditure. The claim can be a wage, dividend, pension, UBI, or ownership.
No claim = no buyer.
AI + humanoid robots give us the tech for abundance. Degrowth forces us to decide who gets the income. The market won’t decide — it optimizes efficiency, not fairness. “Efficient” may mean 10% work, 90% don’t, unless we rewrite the rules on taxes, ownership, and distribution.
That’s why “who buys when jobs die” is the central economic question of the next 20 years.
