My premise for a basic I come is that most of the work we do is simply more than necessary. My thought is that a lot of people will be shut out because many entry level jobs and jobs that require minimal training will continue to get automated and disappear as we move towards the future. We need to make sure those who won't be able to find a job don't starve.

Maybe we ought to bring in wealthy people in for experiment. What makes them get up in the morning and work when they could just sleep all day? Why does Bill Gates still care about Microsoft even though it represents an ever decreasing portion of his wealth?

Of course, we will have tons of free riders but that's the price we pay. Also we don't care because any welfare system will have free riders.
