Question Author
Thank u Totbot.
But dont you think I havent already been on Wikipedia for the answer ?
Although I have used that excellent web for years --- the enclopaedic pot of knowlege for the permanatly ignorant and confused ............ I still found it easy on the wiki submission to get bogged down in professional and technical moneyspeak which gave me an overview but not in very simple prose. I think you summed it up admirably.
My question, was, in any event ,meant to be humourous and we all know that you dont ask questions about these people ..... the seriously rich .... and how they do it ..... cause they wont tell you. !!!
