Hahaha !! It's true. In fact, I think some celebrities (minority) have managed to live with fame. Most of them, however, have started in the music industry as an adult. Amy was very young, perhaps too much. I noticed that almost all, of course there are exceptions, but almost every star who started young person or child, have struggled to get by.
Britney Spears, Lindsay Lohan, Miley Cyrus. I don't know about you, but I'm totally against child stars. This is not an element in which you can grow healthy. A 15 year old who is known around the world, which was the home school or correspondence that has never had a stable life, too busy traveling for concerts and in addition have millions of dollars in bank, it's clear (and normal) that is too much to endure.
macaulay culkin is a classic example of a child star where it went wrong.
it all about how much $$$ the parents can make for them at the end of the day.
