Thanks to Scott McLoed (TEDx talk at http://www.youtube.com/watch?v=-yA6oTU1emM), I can offer a slight variation on your trenchant observation, Harold.

Scott speaks about how "place-based jobs" may have considerable staying power. Such jobs are difficult to routinize and require a human presence. Some examples would be police, fire fighters, nurses, chefs, beauticians, performing artists, building tradespeople, emergency service workers, and military personnel. These may not be totally immune to standardization/automation, but they are certainly resistant to some degree.

I think this poses an interesting counterpoint to the high-skills/low-skills dichotomy. Not to say that the dichotomy is inaccurate, just that there are some important nuances that we can see now, and hopefully some more will emerge in the future. Thank you for mentioning Ross Dawson's three domains; they offer a very interesting scheme of analysis.
