I think you'll need to clarify your meaning... I didn't mention the ground. I mostly mean that the United States has multiple industries dedicated to figuring out what makes people happy (or at least keeps their joy buttons pushed) and arranges the whole chain of operations to push them and to convince people to do work to make sure they get pushed.

That wealth takes the form of things in the ground, but also influence and the capacity to satisfy the desires of other countries and the people in them. Some of that is powered by processes that use raw materials that are non-renewable and dragged from the ground, but in the United States a lot of it is based on a hugely robust import export economy... Most of the things that push the joy buttons come from China.
