Surely those who did not have a classical education were already "marginalized" (my heart bleeds)... even by their speech. The idea that language always must be develop hyper-naturally sounds contrary to the normal development of languages. In which case, I don't think it's natural to expect languages to develop devoid of direct human interference.

So we have the Pope thinking in German, writing in Latin, and we're denouncing an English translation of a document that hasn't been published yet? Yes, sounds about right. Of course the document will be logical and well-reasoned, with a focus on protecting the poor who are paying more than they otherwise would have to without the rich evading taxes... but naturally - few will bother to read the always poorly translated English document, and no one will read the Latin. But everyone will be sure in their hearts that it's a scheme and a plot or an overstepping of boundaries. Lovely.
