I've said this before, but I keep repeating my viewpoint. At some point, we will have automated too many of the "useful" things to do for there to be enough work in the private sector for everyone. There are only so many cars, houses, gadgets and foods humanity needs, and the efficiency in producing these things just keeps growing. I'm not saying that we are headed for a dystopia where no one has a regular job - quite the opposite - but during a transition period a lot of people will be without work. Arguably this is part of the reason joblessness is so common in the US today. We will have to find some sort of tax system that makes it possible for those who can't participate in the elite to also live their lives, and hopefully contribute with some creative pursuit.
A lot of people will find this transition difficult, because a lot of people simply have no direction in life and just keep doing rote work. When the rote work gradually disappears, they will have to find something sufficiently engaging to do with their lives.
