The limits to growth structure is based on the basic growth structure. And, as should be obvious, nothing grows forever as growth requires resources. Those required resources become a limits to growth.
Based on Toward a General Theory of Societal Collapse which references Tainter's Model.
Once I get the formulas and get this working unfold the story and exercise the 2 stock model and then surface the other two stocks and exercise the mode then.

Leverage Point Modeling (LPM) is a demonstrated approach for improved planning and spending for Operations and Support (O&S) activities. LPM is a continuous-event simulation technique that uses the System Dynamics approach of model building. Dr. Nathaniel Mass championed the potential of LPM, and adapted it for the Department of Defense (DoD) as a tool for jumping to a higher performance curve as a means of offsetting higher costs and declining budgets. The purpose of LPM is to test policies and investments that improve mission capability for a given level of investment or funding. It is particularly used to evaluate investments in component reliability and parts availability. Ref: http://bit.ly/aT44kB
A Tragedy of the Commons situation exists whenever two or more activities, each, which in order to produce results, rely on a shared limited resource. Results for these activities continue to develop as long as their use of the limited resource doesn't exceed the resource limit. Once this limit is reached the results produced by each activity are limited to the level at which the resource is replenished. See also Archetypes.
