Maybe also a good question is "what should they do". A lot of jobs are rubbish. That opinion rubs people the wrong way for totally acceptable reasons, but only a hundred years ago, around 90% of people were farmers. Today it's 2%. I think it's fair to say that the cataclysmic effect that our human economy is having on the planet can not last in it's current configuration. Most people should be employed in building and maintaining the planetary biome... in other words, they should be: farmers, only a sort of high-tech, hi-fi, scientific mercenary warrior type of farmer. A plumber for example - the world will always need those - ought to be primarily concerned with diverting waste as a source feed for soil, in a clean and efficient way: a hero. But most jobs exist under a 100 year old paradigm which will change rather quickly. You might say they are "soon to be farmers" - that's the best case scenario. Other's would have us all be mercenaries and go out in a blaze of glory. Not me.
