There were red faces at one of Britain’s biggest banks recently. They had accepted a telephone order to buy ￡100,000 worth of shares from a 15-year-old schoolboy (they thought he was 21). The shares fell in value and the schoolboy was unable to pay up. The bank lost ￡20,000 on the deal which it cannot get back, because, for one thing, the young boy does not have the money, for another, being under 18, he is not legally liable for his debts. If the shares had risen in value by the same amount that they fell, he would have pocketed ￡20,000 profit. It certainly is better than delivering the morning newspaper. In another case, a boy of 14 found, in his grandmother’s house, a suitcase full of foreign banknotes. But they were now not used in their country of origin or anywhere else. This young boy headed straight to the nearest bank with his pockets filled with notes. The cashiers did not realize the country in question had reduced the value of its currency by 90%. They exchanged the notes at their face value at the current exchange rate. In three days, before he was found out, he took ￡200,000 from nine different banks. Amazingly, he had already spent more than half of this before the police caught up with him. Because he is also under 18 the banks have kissed goodbye to a lot of money, and several cashiers have lost their jobs.

Should we admire these youngsters for being enterprising and showing initiative or condemn them for their dishonesty? Maybe they had managed for years with tiny amounts of pocket money that they got from tight-fisted parents. Maybe they had done Saturday jobs for peanuts. It is hardly surprising, given the expensive things that young people want to buy, such as fashionable running shoes and computer games, if they sometimes think up more imaginative ways of making money than delivering newspapers. These youngsters saw the chance to make a lot of money and took it.

Another recent story which should give us food for thought is the case of the man who paid his six-year-old daughter￡300 a week pocket money. He then charged her for the food she ate a few coins for her piggy bank（存钱灌）“She will soon learn the value of money, ” he said. “There’s no such thing as a free lunch. Everything has to be paid for and the sooner she learns that the better.” At the other extreme there are fond parents who provide free bed and board for their grown-up children, While even the most hard-hearted parents might hesitate to throw their children out on the streets, we all know of people in their twenties who still shamelessly live off their parents. Surely there comes a time when everyone has to leave the parental nest, look after themselves and pay their own way in life. But when is it?
