I think it's too broad of a generalization that all rich people are snooty and spoiled. I live in a wealthy suburb of LA and yes, my community is known for outlandishly expensive homes, but that doesn't mean that
all of us are "without a soul" or "lost." My mom and dad, for instance, didn't earn their fortune by sitting on their butts and collecting money from people they cheated or rich relatives who deceased. Instead, they immigrated here from very poor towns in China and made it for themselves through hard work and determination. They have always taught me the value of money and of work, and they make sure I understand what it is like to be poor.
However, I do agree somewhat with
rhiannonmars; I used to have friends whose mom's didn't work and did nothing all day about complain about the kids, get pedicures, and go to Sak's. These kids end up being messed up out of their minds, and it's scary to know that these kids will possibly end up doing drugs, just because they have the money and the time. I make sure to pick my friends carefully, because I know it can be easy to fall into the hole of materialism, especially at my high school.
So yes, LA can be superficial, but I think it depends on where you go. There are many artsy people who don't go for the Juicy sweats and fake tans, and if you can look beyond the surface, LA can be quite nice. May I suggest Santa Monica Pier? 3rd Street Promenade? Manhattan Beach? Like I said, if you can look beyond the few who ruin it for the rest, then LA can be quite nice. Everywhere you go, there are a upsides and downsides.
