Why do you say that?
'Cause of the cost of living?
yes, cost of living is completely unreasonable
it is beyond ridiculous. hopefully that will improve as it seems real estate is coming back down to earth somewhat
also, it is overcrowded. the traffic can almost drive you crazy, which means you better live close to your job- but the housing expenses nearly make that prohibitive unless you make a lot of $
also, there is a lot ugliness- the homeless (I'm sympathetic to large extent, but it is disheartening to see them all the time) and pollution.
about two months back, i saw a homeless guy taking a shit in broad daylight near the intersection of Lincoln and Venice. WTF?!?!
