You're basically talking about the "heart transplant problem." Suppose you have zero dollars and no job and you need a heart transplant which will cost $200,000, which will cause you to live for another two years, or else you will die today. The government can't afford to pay for that -- people can say "death panels" all day long but the fact is that with the current state of medicine and technology we cannot save everyone, and it is not productive to bankrupt the government paying for measures that are more expensive than they are effective. Moreover, the fairest way to distribute government services is to give the same amount to everyone. If you need more than that amount, seek charity. There is a point past which government cannot fix every problem, and we can't calibrate society to the level of the "most disabled person."
> I guess by the second point I mean the short term unemployed more than the "poor" per se. Consider a person who has just graduated from a university in SF and wants to remain there while they look for a job in SV. If they can't afford this , they might have to move to a poor area with less opportunity.
So how is that different with a basic income than it is today?
