PIS The Personal Independence System is a lifestyle where one strives to become as self-sufficient as possible in regard to all survival necessities. So that in case of a complete collapse of the world-wide Profit Wage Economic System, one could still survive nicely without a job and without government, money, credit or barter. It is about due again. A. First get out of debt, one way or another. Save up some money and buy some land and build a shelter from the materials already there.
Shelters take many forms.
Grow your own food and wool, down and leather for clothing. Become a nomad. For the things that you can't provide for yourself, cooperate with other PIS people to produce them. The Priceless Economic System is an economic system where all work is done by volunteers and all products and services are free of charge to everyone. It is more than that.
