In another comment I mentioned The Second Machine Age. It goes into the ideas in this article, but at the end it concludes that this "superstar" economy will invariably concentrate wealth. There will also be more return on equity and lower labor rates. So he concludes a minimum income is part of the answer. I don't think this is right though. While technology does allow one provider of something, let's say the best teacher, to provide teaching all around the world online; whereas in the past you had to use whatever teachers were in your area. But at the same time, it's easier to start a new business. Someone wanting to start a new steel mill had higher barriers to entry than someone with a new idea to use GPS on phones to track parking places or something. Technological revolutions like the adoption of agriculture or the industrial revolution always shake things up. I'm not ready to accept calls for socialistic policies. But I don't dismiss them as simple "moochers" either. It do opponents of socialism well to learn about this stuff b/c these technological arguments for socialism will increase, and we need to resist them.
