I don't get how people keep saying this. A UBI is effectively a tax credit. You fund it with higher nominal rates. These mostly cancel out for working people, netting to zero in the middle. People at the top pay on net so that people at the bottom receive on net.
It's completely sustainable and is effectively just a simplification and improvement of the status quo of having unemployment insurance and a bunch of means-tested benefits for low income people, but without the poverty traps, perverse incentives and excessive bureaucracy.
