Alcoholics Anonymous is a real-world example of network abundance. It is based on a notion that members can help maintain their sobriety by helping others stay sober. The more members it has, the greater its capacity to help even more members. Over time, it has evolved to address other addictive problems as well. It charges no dues, takes no names, generates no transactions, so it is flies completely "under the radar" of the transactional model of health care. Members who achieve sobriety not only help themselves, but also their families, their communities, and their descendents. AA can be seen in terms of an "epidemic of health" - a health-inducing idea that is self-propagating and self-generating.

Networks can change things from being scarce ("we don't have enough counsellors to handle all our alcoholics - we need more money") to abundance (AA members help each other help themselves - the more members, the more helpers). If we can flip our thinking from "too many problems, not enough money" to models that are self-organizing and self-propagating, we may find that problems that seemed insurmoutable or too costly can be surprisingly self-reliant.

When a system flips to this self-organizing, self-propagating mode, we will call this Network Abundance. Wikipedia is an example of this, with millions of articles in dozens of language submitted and edited by its own readers. eBay has an internal market of 150 million buyers and sellers.

Jonas Salk suggested that the way forward in our health care system was to create an Epidemic of Health. Martin Seligman and others have created the field of Positive Psychology by balancing the disease-focused DSM taxonomy to a positive taxonomy of Character Strengths and Virtues. 

An epidemic of health would entail balancing our current disease-based taxonomy with a "positive flip" analagous to what Character Strengths and Virtues is to DSM in psychology.  The Unified Medical Language System (UMLS) contains over 5 million medical concepts around the notion of disease.  Creating a language of health would be a critical step towards understanding an epidemic of health.
