Simulation governance is an approach to governance which most closely matches Plato's vision of philosopher kings while mitigating the weakness of that approach. Plato described philosopher kings as rulers who ruled reliabiliy with wisdom and knowledge while living a simple life. However, the human element is both a vector for corruption in the leaders and means that citizens of a state will not naturally act in accordance to the vision of these philosopher kings. Modern advances beyond what Plato could have imagined have come to a point where they can enable the larger vision of reliable governance through knowledge and reasoning possible. Computers are able to execute codified knowledge consistantly and repeatability as they are programmed.
The other part which has not been possible before is the alignment of organizations and the citizens to the larger social objectives. Technology has enable the monitoring of the operations of society as well as maintaining a direct link to the individual citizens in a society. While this technology is immature, it will continue to be vulnerable to be utilized as a weapon by groups to subjugate the larger population. We can see this when there are abuses in surveleance without a justifiable overall benefit to the population. However as the correct checks and balances are put in place, these same technologies can be used to create a caring society which both recognizes the innate development patterns of individuals and is able to utilize that knowledge to steer individuals in directions that is both pleasent to the individual as well as useful to the society as a whole.
Corruption occurs when incentives for a particular group of individuals do not correlate with the greater social good. In instances like DuPont's teflon cover-up, the incentives of the executives and decision makers inside the company were at odds with the public good. And when cases like this are procecuted, many complicit individuals escaped unscathed since they were only a small piece of the mechanism. The is compounded by the fact that both the corporate structure as well as the incentives stay in place. In effect, while there are incremental agreements and monitoring, the same structure is in place for a repeat to happen with a new unregulated chemical like C8 was when it was in production.
One of the reasons why there are limited actions available against these companies is because they make up a large part of the economic supply chain of not only the country but of the world. Much of the operations and processes are siloed in the company itself without an easy way to replicate outside of it.
