In 1930, Keynes predicted his grandchildren would work fifteen-hour weeks. Productivity had been doubling every generation. The math was straightforward.
Where the surplus went
Keynes was right about productivity. American workers in 2025 produce six times the output per hour of their 1930 counterparts. They work roughly the same hours. The difference is not a policy failure. It is a system feature. Capitalism does not convert productivity into freedom. It converts productivity into capital.
We are not Marxists, though we have read Marx and find his description of capital’s internal dynamics more useful for explaining 2008 than anything the economics departments produced. We are not utopians, though we find it strange that the word applies to us and not to people who believe infinite growth runs indefinitely on a finite planet. We are systems theorists, and from a timeline longer than the electoral cycle, what the social democrats call reform looks like palliative care.
The cycle that keeps cycling
Karl Polanyi, the Hungarian economic historian who studied how markets reshape the societies that create them, identified it in 1944: the market mechanism produces a counter-movement from society, which produces a counter-counter-movement from capital. You regulate. Capital adapts. Each cycle concentrates wealth slightly more. The Nordic model is the most successful regulation in the current cycle. It is still inside a cycle that has not stopped cycling.
AI is the current acceleration. A technology automating cognitive labor at scale, arriving inside a system that routes the gains to owners. The Chicago school says the market will create jobs we cannot imagine. We are not comforted by the word may applied to the livelihoods of billions.
Climate change is a market externality so large that internalizing it would reprice everything. Correct every price to reflect every cost and the economy becomes unrecognizable. That economy is what we are proposing. Not ideology. Arithmetic.
Where we concede ground: Every 20th-century attempt at non-capitalist economy produced authoritarianism, scarcity, or both.
What would change our mind: The full social-democratic program surviving three changes of government with top-1% wealth share below 15%.
