They won't listen, anon.
The problem is not whether or not people know they are corrupt. The problem is that people believe they will benefit from a corrupt system. For many, particularly in urban environments, acting and being nice or compassionate is purely a social ploy for exploitation. In an environment with thousands of faces every day - being nice is a platitude. No one has the time or concern to consider others as there are just too many.
They pretend to care about such things as integrity and honesty - but only insofar as calling someone else out for a lack of it can give you an advantage. It isn't about being a good person - it is about protecting your own advantage while assailing others.
Expanded to tribal politics, they will defend any criminal behavior if it benefits the tribe or its goals as they see it. They don't really care how corrupt it is - just so long as they are able to call the shots.
In order for them to care, they have to get hurt by those policies. Since we do not have peoppe willing to stand on principle, we will instead suffer the pain. Though I doubt that will be enough, honestly. We shall see, though.
