Ok, cool, seems like we're thinking along similar lines :-) The problem I see, however, is perhaps different to the one you pose. As distasteful as this sounds, I suggest that perhaps the "average" person is ill equipped to deal with those more interesting and rewarding jobs, given that they're likely to require significant technical or creative skills.
Can we bring "the masses", as it were, up to the levels of talent and expertise we'll require in the future, or is there a limit to how good our education and training can be? Will we reach a point where a small number of people are, effectively, supporting the majority? A mini version of this seems to be happening in some Western countries with people who've lived their entire lives on welfare. Perhaps the future is just one where more of us end up on welfare and the government keeps us going on the spoils of the extremely smart and/or powerful.
