So, you’re proposing something like UBI but without the U and with far more bureaucracy? Sorry, no, the U is the most important part, and extra bureaucracy is no consolation prize.
In your piece you expound on the beauty of simplicity of ideas. Then why do you take a simple and elegant idea like UBI and seek to complicate it with targeting and bureaucracy? E=mc2 understands that all energy is energy. So does UBI. DDI, as you describe it, seeks to differentiate forms of energy and decide which forms of energy are “worthy” of income.
Jobs do not equal work. They are only a part of work. To use physics as you did, work is mass times distance moved, whether it’s done for a salary or a sale or for personal joy. Life is work, from the labor market to childrearing to voting to personal errands and hygiene maintenance, and the simplest way to make sure all of this valuable work is rewarded and that the worthy in society get the income guarantee they deserve is to realize that all are worthy of basic survival and to reward all of that work unconditionally to that level of income guarantee.
Look inside at where this urge to target and paternalize the income to the “worthy" comes from, and I suspect you’ll find at the heart of it is a distrust of your fellow human beings, with the implied superiority of those you would deem worthy of income and who’s worthy of apportioning the income. It’s very common. It’s trained into us, this idea of the good people and the bad people, the worthy and unworthy. It’s nonsense, though, and it must be unlearned.
Lastly, it occurs to me that your proposal is not all that different in spirit from proposals for a Federal Job Guarantee, which is an idea that already has a lot of political support. Maybe look into that as something you could get behind without having to create and build a new idea, acronym, and movement. But also, maybe consider reading this other piece I wrote on why a Job Guarantee with no UBI foundation beneath it is also a mistake…
