Why is this on the front page? Propaganda. More people move to cali than move out (only watched the first bit)
I only looked at your last two links but while less people are moving to cali, it isn't less people than than those that are moving out. Other factors mentioned above also contributed for the decline.
Honestly though, why do people mention this as a problem. I can only hope it becomes less populated. You could go to death valley on a summer tuesday afternoon and there is still a crowd somewhere.
