How Much Would a More Generous UBI Cost?

A family of four would be 10 grand up a year. That's really, really impressive. So how much would a more generous UBI cost? Do we have numbers in regard to that? I've stuck to my favourite model, which is the introductory one because I think it's feasible and the game changer in terms of equality. There are, in that same paper, Model 2 and Model 3, which are much more extensive. For that costing, which they have done, there's all sorts of other well taxation and other bits and bobs that need to be configured. And also the taxes will become radically reconfigured.
