I really can't figure it out - it should be booming for visitors - new blood, variety, whatever. I'll say this, stupid as it might sound: traffic (and lack of any kind of easy and generally-used public transportation) and the 'flakiness' factor - if something becomes even the least inconvenient for many of us here in LaLa Land, we 'blow it off' no pun intended, and stay home and chill.
I'm not defending the attitude, just seeking to explain the behavior.
