Fred: The "need" for services and goods you mentioned brought to mind a true story.

When I lived on an island of 300 people (no electricity, city water or car ferry) we had no doctor for the first five years we were there. As a result, people focussed on preventative medicine, diet, herbs etc. We also gave birth at home, helping each other. There was no problem we couldn't deal with.

Finally, a doctor came to live amongst us. He even built a cute little clinic that was open two or three days a week. Well, all of a sudden everyone needed a doctor. His clinic was full every day it was open. It was if the entire community forgot that we once took care of each other.

Go figure...
