I questioned the value of doing this when something like public healthcare is working very well in Canada, where it operates much more cost effectively than the US public/private mess, and it has been for a long long time. And we're right next to the US. Yet there has been little progress adopting a similar system in the US.
I'm not sure if just getting examples of it working will be a sufficient motivator that they hope it will be. But I guess public healthcare is old hat now and not in need of scientific study for it's efficacy, just political will which is much more expensive and involved than running social experiments.

I had a similar initial question, since I heard once that Germans (?) already have a basic income system in place, though possibly only for the poor ($500/month plus housing or something like that). Though I suppose "that's Germans, not us" or what not.
