Resilience economics continues to uphold the elements of previous economic models that offer continued value: freedom and openness from capitalism at its best; equality and a safety net from socialism's intent. But it's not just another form of "mixed economy" or "social democracy." The focus is on something entirely new: decentralized diversity as a way of managing the unexpected.
Decentralized diversity (what we sometimes call the "polyculture" model) means setting the rules so that no one institution or approach to solving a problem/meeting a need ever becomes overwhelmingly dominant. This comes at a cost to efficiency, but efficiency only works when there are no bumps in the road. Redundancy works out better in times of chaos and uncertainty -- backups and alternatives and slack in the system able to counter momentary failures.
It generates less wealth than traditional capitalism would, at least when it was working well, but is far less prone to wild swings, and has an inherent safety net (what designers call "graceful failure") to cushion downturns.
