MIT economist Robert Solow demonstrated that nearly 90 percent of productivity growth in the first half of the 20th century was attributable to “technical change” — a catch-all term encompassing technological innovation, accumulated scientific knowledge, improvements in education, and infrastructure. In other words, the overwhelming source of modern economic output is not the labor any individual performs today — it is the accumulated inheritance of every generation before.
This is the collective wealth of the commons — land, natural resources, and the wealth created by past generations — currently captured by a small portion of those who inherit or capitalize on it. Reframing UBI away from poverty relief and toward a “rightful share” of collective wealth shifts the debate toward questions of justice and ownership.
This is not a fringe position. Thomas Paine argued in 1797 that the earth is the common inheritance of all. Alaska has implemented a version of this logic since 1982 through its Permanent Fund Dividend, which is widely understood not as welfare but as a dividend of shared resources.
So the first answer to “where does the money come from” is: from the commons that everyone contributes to and that is currently privatized without compensation to the public.
A vast volume of real productive activity — child-rearing, eldercare, community maintenance, mutual aid — generates enormous value that GDP does not count and markets do not pay for.
This is not marginal. It represents hundreds of billions in economic value annually, disproportionately performed by women and absorbed into household and community life while subsidizing the formal economy.
UBI partially recognizes this hidden labor by acknowledging value outside wage systems.
So a second answer is: from recognizing value that already exists but is not compensated.
AI and robotics are generating productivity gains at unprecedented rates. The question is not whether this wealth will be created — it will be. The question is whether it concentrates entirely in shareholder ownership or is distributed more broadly.
These systems are built on publicly funded infrastructure: education systems, research institutions, and shared technological foundations. An automation dividend would return a portion of that productivity to the public.
One model is to tax automated labor at rates comparable to human labor, creating a self-adjusting system: as automation increases, the dividend fund grows automatically.
In this framing, UBI is not a cost — it is a redistribution of surplus already produced.
A $12,000 annual UBI for every American adult would total roughly $3.06 trillion — less than half of current federal spending.
Possible funding mechanisms include value-added taxation, resource rents, sovereign equity stakes in AI-driven firms, and consolidation of existing welfare bureaucracy.
The question “where does the money come from” is not applied consistently. It is rarely asked about defense spending, tax expenditures, or financial-sector interventions that direct large sums toward capital holders.
The asymmetry is not economic — it is interpretive. It reflects which transfers are considered normal and which are scrutinized.
The real question is not whether UBI is affordable, but who receives the value generated by collective infrastructure, and whether that distribution is legitimate.
