You seem to think corruption is part of local culture. In reality corruption is implemented and maintained by foreign colonialists as a tactic to maintain power over local resources. It is coldly planned for in think tanks and other dark corners of foreign colonial democracies
All of us foreign colonialists would much prefer countries to be run by competent adults. There’s far more wealth to be gotten by trading with a state that functions properly, like say, Australia or even India where plenty of corruption exists but is kept in check… compared to the circus that is countries ruled by warring clans and outright 100% corruption like the worst cases in Africa.
Hang on now: someone breaks into my house, strip mines it for anything valuable I have, takes multiple generations of my offspring out of schooling, beats and kills any offspring that request they stop and leave and it’s my fault the kids struggle to organize? And then when they do get “free”, lacking any example or group memory for how to fairly manage things, the worst of the kids take by strength and starve the rest. That’s my fault too?
