Mike, could you not think of a better topic?
Some of our best friends here in North America are British subjects. They left the UK 15 years ago to find employment here in the USA, and became so enormously wealthy that he just traded his Bristish passport for an American one. It all has to do with taxation of the (American) fortune, and his wife and daughters inheritance. They have told us that they left the UK mainly because she was from a very aristocratic family; and he was from the "wrong side" of London. Something to do with class distinctions and not being accepted.
His biotech company here in New York went public and he became a millionaire overnight. His picture is always in the local papers as the new " leader of the tech stocks" l Pity we did not buy the company stocks when they were pennies.
Anyway, they visit the UK every year and seem to be very much at home in the USA. His wife still cannot part with her British passport, and their three daughter were all born in the USA and have dual citizenship. He has a definitive "cockney" accent, and his wifes speaks the "Kings English"; daughters have a crisp North American accent.
They are staunch Royal supporters ( we get all the monarchy dirt from them).
