What terrible environment? She doesn't live in Uganda or anything like that. There are people who are born in far worse conditions and are now very well. But whatever some people just have a bad personality and even if they're financially stable etc they become bad parents anyway.
I don't know about you, but being carted around from set to set, having paparazzi chase you around, having a mother who probably doesn't know what she's doing (I can't say this accurately, but raising a kid isn't like caring for BABY-B-REAL), and growing up only to discover the internet pictures involving your "aunt" is just as bad a living condition as growing up in a 3rd world country. I can only imagine that this kid will probably end up getting famous in 10 years BECAUSE he/she is the daughter of Jamie Spears... only to get knocked up and have another child.
And the vicious cycle continues.
EDIT: Oh hey, iCarly's on right now!
