Computer programmer David Jones earns £35,000 a year designing new computer games, yet he cannot find a bank ready to let him have a credit card(信用卡). Instead, he has been told to wait another two years, until he is 18. The 16­year­old works for a small firm in Liverpool, where the problem of most young people of his age is finding a job. David' s firm releases(推出) two new games for the fast growing computer market each month.

But David's biggest headache is what to do with his money. Even though he earns a lot, he cannot drive a car, take out a mortgage(抵押贷款),or get credit cards. David got his job with the Liverpool­based company four months ago, a year after leaving school with six O­levels and working for a time in a computer shop.“I got the job because the people who run the firm knew I had already written some programs,”he said. David spends some of his money on records and clothes, and gives his mother 50 pounds a week. But most of his spare time is spent working.

“Unfortunately, computing was not part of our studies at school,”he said.“But I had been studying it in books and magazines for four years in my spare time. I knew what I wanted to do and never considered staying on at school. Most people in this business are fairly young, anyway.”David added:“I would like to earn a million and I suppose early retirement(退休) is a possibility. You never know when the market might disappear.”
