Among all the possible reactions to news of corruption (of any sort) I've come to the opinion that humorous-resignation normalizes corruption and is, therefore, just as corrupt.
In fact, if I were a bad guy, I'd hire people to leave comments of "The system is broken", "This is normal", "Everyone does it", "There's no way to stop it", and rebuff anyone that proposes solutions. "[Your solution] won't be enough because..."
I generally agree with you but not on that point. I don't blame people for checking out. Fighting the wrongness of the world is just extremely tiresome. At some point, people change themselves instead. They stop trying to fruitlessly change things and move on with their lives, often with the goal to make a ton of money so they can isolate themselves from the rotten society.
Sometimes the only healthy way to react to something is to laugh at the absurdity of it as if you were a sociopathic Joker. It's a coping mechanism for dealing with an imperfect unfixable reality.
