It is a lifestyle in which the family wants to meet their own needs; without having to acquire the product in any store. They want to provide what is necessary to preserve their existence, and they are usually families that have a farm to obtain food, they provide solar energy, their water, and even make their clothes.
These families aim never to use the money or prefer to exchange for some product they need. While they fulfill the vision of not living for money, they sustain themselves by selling the food product and thus acquire what they may need, for example, medicines.
Self-sustaining families like to live apart from the system that we lived in today, like depending on a job to satisfy your needs and even be the technology, which today seems fundamental to live. Even in cities, people with a patio can harvest, to be a self-sustaining family, and today these types of families are growing, very little, but growing.
