"According to Tainter, societies become more complex as they try to solve problems. Social complexity can be recognized by numerous differentiated and specialised social and economic roles and many mechanisms through which they are coordinated, and by reliance on symbolic and abstract communication, and the existence of a class of information producers and analysts who are not involved in primary resource production. Such complexity requires a substantial "energy" subsidy (meaning the consumption of resources, or other forms of wealth). …When a society confronts a "problem," such as a shortage of energy, or difficulty in gaining access to it, it tends to create new layers of bureaucracy, infrastructure, or social class to address the challenge. … Tainter argues that sustainability or collapse of societies follow from the success or failure of problem-solving institutions and that societies collapse when their investments in social complexity and their "energy subsidies" reach a point of diminishing marginal returns. He recognizes collapse when a society rapidly sheds a significant portion of its complexity.” Wikipedia summary

*The idea of arming K12 teachers is a good example of how societies "scan" for less complex, less initially costly solutions, thatalso further distribute control, during simplification.
