It is difficult to phrase this without sounding a bit odd, but I have a pal who left Iran under similar circumstances to Morishi. Basically the child of an educated, upper middle class, professional parents. (The type who feared for their lives after the cultural revolution)
That class of society were often educated in England. They certainly had a very western outlook in their views, aspirations, call it what you like. But the Iran we now think of is a billion miles away from the Iran they lived and thrived in 40 odd years ago.
I guess is was similar to to the upper middle class in India under the Raj. They "felt" British.
