How do we distribute finite resources in complex contexts?
Pool, Cap & Mutualize
source
Things that get used up cannot be made available indefinitely to everyone. A sustainable distribution practice that partially links “giving” and “taking” (but doesn’t de-couple them) must combine the following three elements: pooling what is available, capping how much of it can be used and apportioning it in a spirit of solidarity. This means that everyone who can must contribute. What they receive, however, is not linked to the size of their contribution.
# Examples
- Local exchange trading systems 
, especially when the exchange is freely negotiated and not tied to set amounts.
- Social security systems to which people contribute over their lives, based on income, but whose later benefits are not precisely correlate with what they paid in.
- Community-supported health insurance providers such as Artabana and Solidago , which which pool participant contributions but mutualize payouts are based on individual need.
