Wealth can also be linked to having a product someone wants. Look at Bill Gates, who created software to make home computers easier to use. Home
computers are not a necessity, but most everyone has them. This has made Bill Gates extremely wealthy without mining for resources.
The founder of Dominoes Pizza is a billionaire, as he found college kids wanted the product delivered to them. Very few places did that, and he filled
a niche with an inexpensive product. Again, no resources were mined, and people do not need pizza to live on (although the dorm food may give one
reason to think otherwise).
Those are two of many ideas that happened with a product that is not needed to live on. (Hula-Hoops, Mood Rings, Pet Rocks, Slinky's, Tootsie Rolls,
etc all products that made someone vastly wealthy.)
