There has been a good deal of discussion regarding the proposed Universal Basic Income (UBI). Much of these discussions have revolved around the moral and ethical reasoning in support of a UBI. Personally I don't think any moral or ethical argument for the right to a Universal Basic Income can hold water anymore than moral or ethical arguments for the right to health care do.

This leaves us with only the pragmatic or utilitarian arguments. 

Several questions strike me as needing answers in order to proceed.

Who will be entitled to a UBI?

What will the criteria be, and who will be responsible for formulating said criteria?

How will such a monumental and gargantuan project be funded and overseen?

If we leave off the arguments regarding the moral and ethical imperative to to create such a program, these become the most vexing questions.
