Our current economic sector indicators, especially the "service sector," needs major revision.
100 years ago, one could see indicators for cotton, barley, oats, and a zillion other agricultural products, while manufacturing was in one category. Today we have about 25 manufacturing sub-sectors, created by the Bureau of Labor. See the list here.
And then there's the "service sector," which includes the kid working the ice cream machine at McDonald's, and a ton of professionals and knowledge workers in various occupational sectors.
The reason, of course, is that without the proper categories, the eoncomy and economic output cannot be correctly measured.
So here's a first stab:
-Self employed entrepreneurs
-Training and Education
-Data analysis and data mining
-Computer and IT services (services, not hardware)
-Agricultural services and consulting
-Manufacturing services and consulting
-Government and government services and consulting
OK, now YOU add to my list.
