No, but that isn't the only tool or lever to pull. It's an idea around a rising tide lifts all boats where an extra $1k a month or baseline income could bridge gaps so instead of choosing between food, car, and insurance this month the household can cover all 3 and maybe get out for some ice cream and have a human experience.
There are fair criticisms of UBI but it would not be acting in a vacuum. There could be policy and actions to support the goals of UBI. Everything is more complicated than it seems.
