In Hollywood, everybody wants to be rich, famous, and beautiful. Nobody wants to be old, unknown, and poor. For Hollywood kids, life can be difficult because they grow up in such an unreal atmosphere. Their parents are ambitious, and the children are part of the parents' ambitions. Parents pay for extravagant parties, expensive cars, and designer clothes. When every dream can come true, kids learn the value of nothing because they have everything. A 
13-year-old boy, Trent Maguire, has a driver, credit cards, and unlimited cash to do what he wants when he wants. 'One day, I'll earn more than my Dad,' he boasts. Parents buy care and attention for their children because they have no time to give it themselves. Amanda's mother employs a personal trainer, a nutritionist, a bodyguard/ chauffeur, a singing coach, and a counsellor to look after all her 15-year-old daughter's needs. Often there is no parent at home most days, so children I decide whether to make their own meals or go out to restaurants, when to watch television or do homework. They 
organize their own social lives. They play no childhood games. They become adults before they're ready. Hollywood has always been the city of dreams. The kids in \ L.A. live unreal lives where money, beauty, and pleasure are I the only gods. Will children around the world soon start to 
think the same? Or do they already? " 

"Looks are very important in Hollywood. If you're good-looking, you'll go far. I want to be a beautician. You grow up really fast in L.A. Everyone is in a rush to be an adult, to be going to clubs. It's not cool to be a kid." Mijanou, aged 18 

"I live in a hotel and when I come home from school, there are maybe 80 people who say 'Good day' to me. It's their job to say that. In the bathroom there are 
mirrors everywhere. I love looking at myself. I can spend five hours doing my hair and posing. I'm going to be a model. " Emily, aged 10 

" I've wanted to get my nose done since I was 12. My friends started having plastic surgery and liposuction during my freshman year of high school. My nose cost $10,000. But it was worth it. It changed my life. I'm gonna get into the movies." Lindsey, aged 18 

" Everyone thinks Hollywood is so glamorous, tout I have news for you. It is really dangerous growing up in L.A. People have guns. Sometimes I think I'm going crazy. I'm going to get out of here jUSt as SOOn as I Can. " Zavier,aged 18
