Life really should be one long journey of joy for children born with a world of wealth at their feet. Internationally famous child doctor Robert Coles is the world’s top expert on the influence of money on children. He has written a well-known book on the subject The privileged Ones, and his research shows that too much money in the family can cause as many problems as too little. "Obviously there are certain advantages to being rich," says the 53-year-old doctor, "such as better health, education and future work prospects. But most important is the quality of family life. Money can’t buy love." It can buy a lot of other things, however, and that’s where the trouble starts. Rich kids have so much to choose from that they often become confused. Over-indulgence (娇惯) by their parents can make them spoilt. They tend to travel more than other children, from home to home and country to country, which causes feelings of restlessness. "But privileged children do have a better sense of their positions in the world," adds Mr. Coles, "and they are more self-assured. The rich children inherit the property from their parents and enjoy a high income. So money will never be one of their problems. However, they will have a sense of isolation," warns Dr. Coles, "and they could suffer from the hardship of not being able to deal with the everyday world because they will never really be given the chance. Everything they have achieved is because of an accident of birth. There can be no tremendous inner satisfaction about that." Today’s wealthy parents perhaps realize their riches can be more of a heavy load than a happiness to their children. So the first thing for them to consider is to ensure that their families are as rich in love as they are in money.
