Industry has always tried to get more "productive"... more product per man-hour of labor... Machines to make things in great quantities at low cost. Machines to take the place of many workers. What is left for displaced workers to do? And when our economy settles out after this "adjustment", we may find economic activity some 20-40% BELOW the 2007 "borrow and spend" peak. We may find that there are not enough jobs available, regardless. What is to be done about the permanently unemployed?
