What if you saw something bad was happening, like a burglar entering a house, so you found a cop, you told the cop — and then their shift ended and they went home. It would be frustrating. The odds that you would give up and leave would increase — the odds that you would continue to care would decrease. You might be a bit demoralized, and with three shift changes for cops every day, burglars would start getting bolder and bolder.

Welcome to the demoralizing world of fighting cronyism. You find something that is going wrong, you bring it to the attention of the people who can turn everything around, and then just as they learn how to wield their power and stop the cronies, they move onto a new job.
