I don't see anything unique or novel about the idea of "basic income". We already have it here for hundreds of millions of people here in the USA, some citizens, some not, called SOCIAL SECURITY.
The only difference I see is the idea of spreading the concept to include those who, for any number of reasons, are not gainfully employed.
I don't see this an an option - it is something that sooner or later we are going to HAVE to accept. The simple fact is, as technology becomes more sophisticated, combined with the idea of "off-shoring" jobs here in the USA to take advantage of cheaper labor overseas, there will be less jobs for more and more people. Hungry people are dangerous. I say "feed em" !
