I don't think anyone wants to be employed. They want the money that comes with employment. If you can make get money without employment, like rich kids, for example, I think most people would prefer that.
And you think that once the poor are no longer needed by the rich, the rich will decide to just give them money anyway? We already have dedicated campaigns to make sure people die sick and homeless on the streets when they become obsolete. You think that is not going to get much, much worse?
If AI is so great it can do your job it is good enough to provide for your needs directly by automation. Just buy a robot and a plot of land and you don't have to worry about jobs.
