I presented the BI argument to someone whose judgment I trust and whose opinion I respect, and his response was this: if America agrees to give all of its citizens over the age of 21 $6000+ a year, it had better take actual drastic measures to curtail immigration both legal and illegal, because even more people will come to America (and become citizens) than already do. Those worldwide who make less than that per year, which is hundreds of millions, will think "now we really have nothing to lose by going to America." My response was that the US would have to create stringent guidelines around who exactly could get this money -- people who could clearly prove citizenship, people who had been citizens for X years, etc. But that somewhat defeats the purpose of so-called 'no strings attached' money. Just words for thought. I'm still hashing out what I think about this issue.
