In the future the English of the Upper Class Elites has become more flowery and eloquent, with a twofold purpose. The first purpose is so wealthy sycophants can impress their alien overlords, the Escalusians, and in that effort better position themselves above their human peers. The lower classes have followed suit in their efforts, imitating the speech of the rich and famous, and consequently English has evolved into a more flowery version of its former self.
The second reason is that speaking in such poetic ways allows people to often speak in code, lest the spies of the Escalusians overhear what they are saying. Speaking in code while organizing a rebellion against their alien overlords is a matter of survival, and thus by often speaking in code the flowery speech becomes a camouflage on which mankind plans a rebellion.
