I was born and raised in Los Angeles, and still live here.
I suppose it's a fun place to visit. There are a lot of things to do here. Especially if you have a good amount of money to spend.
Living here is a different story.
Although I have done well and have a nice career, I spent my youth with not a lot of money. Even though my parents had money, when I left home it became really tough to make ends meet until my career took off. So, if you come to Los Angeles without any specialized skills you're going to have a really hard time having any fun. You will simply be working to house and feed yourself, and not much else.
Don't get me wrong, it wasn't all doom and gloom, I had friends to do things with and have some really good memories with. However, if I hadn't been born here, I would not have done so well emotionally, because I wouldn't have had the support of my friends and family to keep me going.
Politically, this state is out of its mind. All the politicians do in this state is try to figure out ways to separate you from your money. They tax EVERYTHING here to death.
