There’s probably a feedback loop: as people have become convinced that the government is only useful for corruption, that becomes an expected perk of the job.
Unfortunately, I don’t see a way out of that loop. Move to a state that still has some civic pride I guess.
The way you get out of that loop is by creating immense pressure from the outside until the governing system breaks, then supervising the reconstruction as an outside power until it can function by itself again. The issue is that there's a very high risk of it suffering malformed development during that reconstruction, or even worse it's abandoned early and never even builds the functionality needed to sustain itself. The risk is so high that people prefer to let the system degrade with the hope that it will eventually halt or in the slimmest chance even regress to a better previous state. Meanwhile the success rate is so low that I can think of a myriad of failures off the top of my head including Panama, the Kingdom Of Italy, Albania, the American South during Reconstruction, and Indonesia with the only success coming to mind being Japan.
