Do you have upset the system in order to rectify it?

So far in Cuckoo's Nest I've noticed that the women have the most power, which doesn't make a lot of sense when you compare it to reality. In addition, if you think of all the different types of characters in Cuckoo's Nest, you have the women, the black boys/other ward guards, and the patients. After the women, the black boys have the most power, and then finally you are left with the predominately white patients (and Cheif). Considering this novel was written in '62, this sequence of power most definately doesn't correspond with the real world when Kesey was writing the novel. The only person that has been upseting this system has been McMurphy: first he resisted the black boys in getting a "shower," then slyly told the Big Nurse he doesn't always follow the rules, and just recently placed a bet that he could offput and upset her. I guess with all of these situations I'm wondering if you have to upset the system in order to make it work. I think this because if the ward is supposed to fix the men, and the people doing the fixing, are people in society are normally beneath them, it would suggest that really the patients have to be put in an enviornment they're not used to, to make any progress. I wouldn't have thought that in order to "fix" a person you would need to put them in a place that is so unlike what they are used to, if ultimately the goal is to create a ward that is like the real world. I can't figure out why Kesey changed the power holder so that it's with the minorities, but it's definately important. So...the question I'm still battleing with is whether you have to upset the system so as to rectify it...especially because the Big Nurse loves the system so much and keeping it as orderly as possible.
