Asimov and others predicted a future where there wouldn't be enough jobs to go aroundubt they saw that as a GOOD thing. Humanity was clever enough to build machines to do all the work, and now we can kick back and enjoy some leisure time. George Jetson had a three-hour workday. But that vision can only work if we view our increased productivity as a benefit to *everyone*, and compensate everyone accordingly: a dividend for being a member of the clever human race (or if you want, a dividend for being a citizen/resident of a first-world nation).
As more jobs are automated, it seems to me that there are three options: 1) we share the wealth, either with a guaranteed income or by raising wages while simultaneously cutting the number of hours people work; 2) we make a lot of fake jobs so that we can pretend that people are earning the money they need to live, and avoid the horrors of socialism (horror! horror!); or 3) a LOT of people drop into poverty.
