This article says it's talking about a universal basic income, and makes the usual point that a completely universal, no-strings-attached income is simple to administer, doesn't have poverty traps, etc. And then, towards the end where it starts looking at numbers, it starts saying things like > But by excluding 45 million retirees who already receive a basic income through Social Security, the cost falls to $2.7 tril…
But, the big problem is the idea that the UBI should initially be sufficient to lift everyone out of poverty. The immediate goal should be to have a UBI which reduces poverty and addresses the fact that capital increasing takes the reward of economic growth, rather than it being broadly distributed. The long-term goal should be to displace and go beyond existing means-tested anti-poverty programs in lifting people out of poverty, but the best way to do that is to build a system that grows naturally.
As an example: eliminate preferential treatment of capital income in income taxation, maintaining otherwise general structure of the existing progressive income tax system, and set aside a portion of the total income tax revenue equal to the initial increase in tax revenue for the "Common Welfare Fund".
90% of the new money in the fund is distributed as UBI by equal division among qualified recipients (e.g., all citizens and LPRs, if that's the group defined to receive the UBI), the remainder is retained as a stabilization fund (with returns on the stabilization fund treated as "new money" in future years, and rules providing for some distribution from the stabilization fund to current benefits to reduce calculated benefit declines.)
Each year, reduce the actual minimum hourly wage from its nominal level (which I'm presuming gets inflation-indexed before this) by 1/2000 of the annual UBI level (for wages covered by overtime mandates, the minimum overtime wage is calculated first, and then reduced for the UBI) -- over time, the UBI displaces the minimum wage.
Other (e.g., means-tested) benefit programs aren't directly eliminated (immediately), but income from the UBI is treated as normal income for both income tax and benefit calculation purposes, so (assuming economic growth such that real tax revenues pre capita increase faster than inflation), even with eligibility criteria indexed for inflation, growing UBI will reduce the proportion of the population eligible for any such programs, eventually to 0 as the UBI crosses the maximum threshold for each program, allowing the programs to be retired.
