I live in LA and I have to say I'm not a big fan of living in California.
9% income tax, 8% sales tax.
It's the mecca of homeless people (as well as car freaks), and it's the mecca of liberals. Real estate prices are high and housing quality is low. The schools generally suck, the air sucks, the water isn't great, the traffic is bad, you get earthquakes occasionally, it's flooded with illegal immigrants, and all of the food has avocado (which I don't care for).
I like the weather, I like the scenery, I like the cars, the night life, the job opportunities, and proximity to the ocean and snow.
But LA (or San Diego or San Francisco) has a ton of drawbacks, big ones... like "You want to live here? You only have a small fortune to your name? He's your rundown shack in a gang infested neighborhood."
