A UBI would need to use progressive taxes to solve.

Given these challenges, some have begun to advocate for “universal basic income” programs, which dispense with trying to identify the poor and instead provide transfers to everyone. A universal basic income program is comparatively straightforward to implement—each individual receives a fixed transfer, regardless of income—so the main challenge is to ensure that each person receives the transfer only once. Although universal basic income programs distribute the same value of transfer to everyone, including the very rich, if they are financed through proportional or progressive taxation, they can still result in a substantial redistribution to the poor.
