Service Industries
Economic data classify anything not mining, manufacturing, agriculture, fishing, forestry, construction, or government as a service -- everything from investment banks to flea markets, almost 80% of the US GNP. Services built and powered by the physical economy constitute the consumption economy.
Exactly what should be classified as a service industry is still subject to debate, so official figures are "squishy." For example, power generation is apt to be classified as a service, although most other services (and almost all "consumers") utterly depend on it.
Of course, mining, manufacturing, construction, and agriculture are huge consumers of resources too. They are mostly "pass through" consumers if they enable use or consumption by their customers.
