Why the Rich Don't Pass Wealth to Their Children
The rich have traditionally passed their wealth on to their children. But an increasing number of billionaires are choosing not to. The reason? They want their children to live on themselves -- and not to turn into spoiled successors.
Nicola Hodick or "superwoman", a famous British billionaire, owing to the fact that she has high-flying jobs and five kids -- has spent her career making a report f 250m. She now seems determined to throw off large parts of it. She already gives away about 25% of her income each year; she has just revealed, in a report on the state: of charity in the city, that she will not be leaving most of the remainder to her children. "I think it is wrong to give too much inherited wealth to children," Horlick told the report's authors. "I will not be leaving all my wealth to my children because that would just ruin their lives. "
She is by no means the first to go public with this conviction. Bill Gates has put an estimated $ 30bil into the Bill and Melinda Gates Foundation. This was supplemented, in 2009,by another $ 24bil also from his friend Warren Buffett.
Buffett has always been colorful, quotably clear on where he stands. His daughter often tells a story of finding herself without change for a car parking ticket -- her father lent her $ 20,then promptly made her write him a check. "To suggest that the children of the wealthy should be just as wealthy," he has said, "is like saying the members of America's 2004 Olympic team should be made up only of the children of the 1980 Olympic team. "
Antia Roddick, the late founder of the Body Shop, told her kids that they would not inherit one penny. The money that she made from the company would go into the Body Shop Foundation, which isn't one of those awful tax shelters, like some in America. It just functions
to take the money and give it away.

B．they want their business to go on healthily
C．they believe too much wealth will harm their children
