There's no such thing as a 'self-sustaining industry'.

They all rely on common transportation infrastructure which they use to ship their materials and goods around and get their employees to work. They all rely on a predictable and fair marketplace whose fairness is governed by the state, and they all rely on people not coming and burning their premises down because they're protected by the state!

Self sustaining means they generate enough revenues to cover their costs. Not that they are closed systems with no interaction with general society.

My point is that they don't feel their costs. Therefore by definition they're all "forever sucking on the public teet."
