It is true that many people are leaving CA because of high taxes, etc. but most of these are people who are blue collar, low paying white collar and lower management positions. Come to LA and look for a house or apartment-costly. The leavers are being replaced by others who have more education, asset, etc., Now this creates it's own problems, but CA will not become a ghost town. However, there are businesses leaving-that is a problem-for places like Texas, Utah, etc., where there is less regulation, etc., Many of these businesses are unhappy when they get there. Quality of life is not always the same, weather, schools, etc., have caused SOME to return to CA and bite the bullet of spending more to live in CA.
I can afford CA so I may be presumptuous, but I'm not leaving CA to live in Idaho, Utah-although we do go to Deer Valley to ski-or any other icy, car fishtailing state.
