Bureaucracy
Bureaucracy is a necessary evil in any society worthy of the name. Without it, people cannot be coordinated at a large scale, but it is an inherently predatory system which tries to grow to consume everything while shirking all responsibility. The bureaucratic drive for order may ensure consistent standards are met for critical goods like food, but chaos is necessary for innovation and growth. Bureaucratic oversight may help prevent mistakes, but many people cannot find God if they are not given the freedom to err and learn from their failures.
If allowed to run amok, the inherent incentives of bureaucracy will drive it to crush freedom, prevent innovation, destroy people, and attempt to supplant God until reality asserts itself and the bureaucracy is destroyed, either by an uprising from within or conquest from without. Like many things in this imperfect world, bureaucracy is both powerful and dangerous, so it must be used with caution.
Thus, while a Just Society will use bureaucracy where necessary, it will make every effort to limit its scope and scale to the greatest extent practical.
A Just Society must ruthlessly exclude bureaucracy from as many facets of society as possible. It may not be possible to fully eliminate bureaucracy in the large-scale production of essential goods which must be regulated to maintain social trust, but no bureaucrat has any business telling people how to decorate their homes. Automation is also a critical capability since a computer can often do the same job as a bureaucrat with much less cost and risk, although automated systems still require human oversight to correct the inevitable errors so they can never fully replace bureaucracy.
Furthermore, since bureaucracies naturally attempt to deflect all responsibility, a Just Society must make and enforce strong laws to prevent this. Since a bureaucracy run amok will inflict great evil on the innocent, it is better to spread the consequences of failure across more bureaucrats than to allow the bureaucratic machine to avoid justice. If no one person can truly be said to be responsible for committing a crime, it is better to hold everyone involved accountable than to give the collective bureaucracy free reign to commit crimes with impunity.
Ultimately, the overarching principle of checks and balances must be used to control the bureaucracy necessary within a Just Society. If done properly, the result will be a small, efficient bureaucracy that works for the people rather than an oppressive, bloated abomination, but like all checks and balances, constant vigilance is necessary to defeat the natural tendency of bureaucracy to break its bonds and devour society.
