Yes, I don't know who in their right minds is thinking basic income will work out well for society based on the predilections of the masses.
Most people do. not. like. to. work. Period.
But work is good for society. Idle hands are the devil's tools after all, and where one finds high unemployment, they are almost certain to find crime, drugs, gangs, single mothers, and most everything else that reasonable people consider a step backwards in civilized society.
Now what's the other side of that coin? Young ambitious hackers that browse HN will have more leeway to easily start startups living in their parents' basements. That's a good thing, and honestly sounds very appealling even to me now (minus the parents and the basement though).
However, you have to do what is best for the most people, and while a few percent will benefit and be able to further contribute, the majority will flounder and sink into degeneracy.
That's the problem with utopian thinking. Reality and human nature always get in the way.
