My observation is that the 13 homeless persons in London found that having the cash gave them time away from the full-time activity of surviving so they could think, reflect and plan, and, it gave them the runway to execute their plan.
This concept of basic income has been occupying my thoughts quite a bit lately, particularly when I venture in to San Francisco. Each time I think about it, as a thought experiment before reading this article, I can see far more good coming from it than harm.
What I think, and seems to be supported by the article, is that giving (for example) $1,000/month to every adult in America would play out like this: A family of 4 would have $24,000 per year guaranteed income. If both parents worked minimum wage jobs earning another $16k each, and I do believe they would, they'd have a household income of $56k on minimum wage jobs. They could situate in a reasonable school district, afford to pay more rent for a safe neighborhood, afford reasonable health care and focus on raising their kids. The kids will do better in school, the family can feed themselves less unhealthy food, there will be less anxiety about the basics and less domestic conflict.
The studies in the article -seem- to support that outcome.
$12,000/year per adult not already on welfare or social security would cost about $2 Trillion per year. To put that into perspective, Social Security costs $1.3 Trillion in 2013. Cost of all social welfare programs was $529 Billion. The GDP came in at around 17 Trillion.
The US could afford it if we really wanted to. So what I'd like to hear are the counter-arguments. Is it inflationary? I'd say it has to be. Is it fair? If every American receives it, regardless of their wealth, then I don't see how it would be unfair. Is it realistic? It seems that the US was pretty close to something along these lines in the 60's and Obama finally got universal health care through. Perhaps it is realistic enough to at least put a true, modern pilot program in place and convince ourselves one way or the other. It really seems better than the alternative: Status quo for the homeless and the poor.
