Computer programmer Brendan Tammy earned &55000 a year by designing new computer games, yet he cannot find a bank prepared to let him have a check card. Instead, he has been told to wait another two years until he is 18.
He works for a small company in Liverpool, where most young people of his age are looking for jobs. Brendan's biggest headache is how to use his money. Though he has high payment, he cannot drive a car, or get credit cards.

I knew what I wanted to do and never considered staying on at school. Most people in this business are fairly young, anyway. 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. "
Why is Brendan so different from other young people of his age？
A．He earns an extremely high payment.
B．He has got a job.
C．He lives at home with his parents.
