I understand how it sounded like I meant that. I only mentioned the particular speeches because they're so well known and I *THINK* they're examples (not completely sure, but it seems likely). I don't know if public speakers and radio/TV announcers tended to be upper-class and from those areas, or if people had to learn to talk that way to get hired, or what. It might have been a trend, and people just learned to talk like that if they wanted to get a speaking job. I like conjecturing about this kind of stuff.
