Concerning the first group, while politicians are obvious candidates, it also includes businessmen, and, on a more local level, teachers, clergymen and policemen. The definition of privacy (according to the OED) states that people should be “free from public attention, as a matter of choice or right.” In my opinion, taking a position of power takes away from this area of privacy. It is proportional, in that at the highest level of power (politicians) your actions will necessarily be of public attention, whereas at the lower level (teachers) the majority of your actions should not be of interest to the public.
