Yes but during the industrial revolution we had a lot of unmet need. Now, we are much better off. I'm not convince there is enough need to justify keeping everyone employed.
Just to be clear, the entire history of humankind is evidence against your theory. You are guessing that something will happen that has never happened before.
That's not as bad as it sounds. Every event has to happen for a first time. But you should realize that you are making a very extreme claim based on nothing more than speculation.
I'm quite probably wrong and I'm also playing devils advocate poorly. What I'm trying to say is we already have almost everything we need. While I can point to many aspects of my life that could be improved upon, I can't point to many where the improvement would result in more and better jobs.
