The Ottoman Empire kind of acknowledged the futility of trying to suppress corruption, opting instead to codify it and set thresholds for excessive abuse. Progressive for its day, it only partially succeeded since enforcement was no less prone to corrupt influence. As the romans famously said, “Quis custodiet ipsos custodes?” Literally: “Who will guard the guards themselves?”

It's why the 3 branches of government worked so well for the US for so long. They each want to protect themselves, and are effectively at odds with each other unless there is almost universal agreement on something.

However that has completely fallen apart with a toothless Congress, and a executive branch that can stack the 3rd branch with similar minded idealogues.
