To clarify What I said at the beginning about not having the code to do it, I was saying that we wouldn't be able to do that, and thus need not worry about the system being like that.
You might be right about revolts and that it only kicks in with culture, I am probably thinking of an older civ, where it was unhappiness that caused rebellions. I just was unsure if long term unhappiness eventually does something other than just reduce the number of active citizens you have...
Well you say that the enclave or NCR doesn't fracture, but both have examples of fracturing, or at the very least coming close to fracturing.
For example in the NCR you have the Tandi ideology which was a kind of anti-capitalist, social responsibility.
You have the Water Merchants of the Hub who seek influence and control and reinstate (or perhaps just try to) the Water standard that was first introduced with bottle caps, after the NCR Gold standard collapsed post BoS War.
You also have the Agricultural/Cattle Barons who seek greater influence in the NCR, who were kept in check by anti monopoly laws under Tandi, but who were slowly eroding those laws after her death, to the point that they had such influence as to be able to 'mis-use' the elite forces of the NCR to protect their interests.
Then in the Enclave you have the Richard Richardson 'faction' you then have the John Henry Eden computer faction and you have the other guy who I think takes over after Eden is eliminated, who I think each approach the 'Ideals' of the Enclave differently.
Now in the story each of these come to 'power' on a clear path because the player eliminates the previous leader, but if that had not happened we could have potentially seen an Enclave civil war as each major leader believes that their way is the right way for the Enclave Ideals to be upheld.
