There will be more middle class moving out of the city -just what is NOT needed as thats the tax base...I'm from California (Riverside County) and lived in LA for 3 years (West Holllywood, Santa Monica and Malibu) Even in the "chic" areas I lived in you had to be carefull - I believe the crime is worse in LA then NYC, more gang problems IMO.
The way it currently is, you have IMO two classes in the city.
You have the poor that mostly rent and treat the property like a toilet.
The other class is the low wealthy level and up. The so called middle class homes in Los Angeles are more costly by far than the homes in suburbs. So a 800 foot home in the inner city could easily have two millionaires in it with a combined income of $250,000 or higher.
Anybody not grandfathered into the area who aren't earning $250k are moving to suburbs, Riverside and such as you say mostly out of necessity, not over people issues so far.
I think Villaraigosa is a bigot with a big mouth, and when he gets going, lots of bad violence will be set off.
Bradley was bad enough when he got on TV after a jury verdict and said "He didn't understand why the people of LA are not rioting".
Villaraigosa will make Farakan and Bradley look like choir boys in a year IMO.
