The idea of UBI is intellectually interesting, and some smart people across the political spectrum have supported versions of it. But when you look at the numbers and the evidence, significant problems emerge.

The basic math: approximately 258 million American adults times $12,000 per year equals about $3.1 trillion annually. Total federal income tax revenue in 2023 was about $2.2 trillion. So UBI at even a modest level would cost more than the entire income tax system generates. You'd need to either massively raise taxes, cut almost all other programs, or print money — each option with severe consequences.

Finland ran one of the most rigorous UBI experiments from 2017-2018, giving 2,000 unemployed people about $685 monthly with no conditions. The result: recipients reported slightly better wellbeing but showed no significant improvement in employment. They didn't start businesses or pursue education at higher rates. A similar experiment in Stockton, California showed modest benefits but was tiny in scale (125 people) and partially funded by private donors.

The labor supply concern is real. The University of Chicago's National Bureau of Economic Research reviewed decades of cash transfer programs and found consistent evidence that unconditional cash payments reduce labor force participation. During the expanded child tax credit payments of 2021, research showed a measurable decrease in work among recipients.

There's also the inflation problem. If everyone receives an extra $1,000 a month, prices adjust upward. Landlords, retailers, and service providers capture much of the transfer through higher prices. You can't distribute more money without producing more goods and services and expect prices to stay the same.

More targeted approaches — earned income tax credits, job training programs, removing occupational licensing barriers — address poverty without the massive fiscal cost, inflationary pressure, and work disincentives of UBI.
