So, if the person discussing this, and presumably the one choosing to be rational, is C, and it must necessarily fight against a selfish, flighty and almost completely uncaring U except in the cases where it percieves a direct benifit, and furthermore is assumed to have complete or nearly complete control over the person, then why be rational? The model described here makes rationality, rather than mere rationalization, literally impossible. Therefore, why try? Or did U's just decide to force their C's into this too, making such a model deterministic in all but name?
