Division of Labore

As stated, the three categories are routine production workers, in-person service workers, and symbolic analysts. All three categories implement technology in some way, the first on a more basic level, with symbolic analysts implementing technology more creatively.
I agree with earlier posts that this is contingent with the four c’s. It is interesting that there are three separate categories, rather than the two, white and blue collar jobs. Technology has implemented all three classes; the poor, the middle class, and the wealthy. Those who work lower wage jobs, and who may not have a good education, still are required to know the basics of technology. It’s everywhere.
