Is 20$/hr enough for frontender in LA?

Hey, working in a broad types of front-end development jobs, I am hearing a much words like starting rate is 25$/hr netto, less is for newbies who don't know what is OOP is and can only make GOTO spagetti code. Others are saying that 20$/hr is normal rate worldwide for any developer. Calculating wage with 20$/hr it is 3200 USD per month on hands which is good for most cities, maybe not for SF / LA due to rent costs. So which rate is fair for you %username%?
