This guideline, "Do work for other people...." contains a good 
idea: barter instead of using currency. Although, using money
earned while working, to pay for goods and services is similar to
a barter system isn't it? In the town where I live, there is 
something similar to a barter system but it is more appropriatly
called a "bar network." Local service workers who frequent the 
same bars don't charge eachother when they visit their places of
business. One will neglect to charge for a meal in exchange for
free cappucino later on. It all works rather well, except one 
small problem. The owner isn't getting paid for any of this.
Well thats what happens when you don't pay a respectful livable
wage.
