I think you're underestimate the number of jobs that can be done with extremely little cognitive skill, and over-estimating the speed with which technology will make them go away. I agree on the education front, but disagree that there are significantly many negative-margin-value people. Personally I think a huge amount of that perception comes from the fact that people just don't fucking move to better economic opportunities. That problem may be solvable as things like distributed call centers and other location-independent work becomes more common.
