Minor correction.
I stated that the bulk of FTs that I have met "of all nationalities" are college educated. Once a North American has the education and sets out to advance in their career, whatever regional accent they may have must either be lost or severely toned down. Otherwise, they don't move up. This is any career from business to education to gov't, etc.
In my case is was the Virginia/Southern accent. People in Virginia always said I had no accent, but then I'd speak with a Yankee and he'd think I was some kind of rube/redneck. And then all that money sitting on the table (I was in sales) went to someone else!
Hence, I lost the accent very quickly. I must admit that it will still slip out after too many Tsing Taos.
I never meant to insinuate that Americans and Canadians were more educated than others. I do not believe this to be the case. It's just that once we have the education, we're under extreme economic pressure to speak correctly.
Subsequently, when you meet us, we all sound alike.
