text: Largely agree with this article, but it omits to mention a few important points.

  One of the most important is that people with no income tend to impose abnormally large costs on the health care system, the police and fire (i.e., first responders) emergency services, and large costs on the judicial system.  Avoiding these costs by reducing their frequency and their severity is one of the huge attractions of these schemes.  There is some suggestion that the schemes may actually save money in the long run.  Perhaps the pilot projects will shed light on that topic.
