[Tremors] How do the people of Perfection Valley survive out there? (Monetarily)

With only fourteen people that live there how does anyone stay in business or make a living? There doesn't seem to be any real businesses there or enough people to keep one afloat.

Melvin and Mindy are kids, they live with their parents.

We already know that Val and Earl are handymen. It's likely that they were drifters that somehow met and became friends, either before or after they came to settle in Perfection. They sleep in the truck which means they don't pay rent or mortgage, which also means they don't have a permanent residence and likely don't pay taxes.

Rhonda is only a Grad Student, and doesn't live there. But she travels to Perfection to work on her assignment. The low importance of that assignment and desolate environment (she's the only one there) suggests a close proximity to a large enough city to have a college.

We know that Walter owns the store. He stocks pretty much everything, suggesting he supplies Perfection as well as the occasional passer-by, a person traveling through either to or from the nearby city.

Old Fred is obviously a sheep farmer. He farms enough to feed himself, and sells wool and mutton.

Wallace and wife are a retired couple, building their own house and living off savings.

Nancy is an artist. She probably sells to the occasional tourist passing through but also likely sells in Bixby, putting her artwork in a consignment shop.

Jim is a doctor, for the town but also likely for a large surrounding area.

I don't recall the rest, but there were jobs even back then by which you could "telecommute", or that were high paying while still allowing for an incredible amount of time off. Engineers can design at home and then lease their work to agencies.
