Human societies and cultures are complex and messy. That means if we want to even begin to start understanding them, we need to simplify. This approach from Harold Jarche, based on David Ronfeldt’s work, is interesting:

Our current triform society is based on families/communities, a public sector, and a private market sector. But this form, dominated by Markets is unable to deal with the complexities we face globally — climate change, pollution, populism/fanaticism, nuclear war, etc. A quadriform society would be primarily guided by the Network form of organizing. We are making some advances in that area but we still have challenges getting beyond nation states and financial markets.
This diagram sums up why I find it so difficult to work within hierarchies: while they're our default form of organising, they're just not very good at dealing with complexity.
