California would see an even bigger influx of folks and with it, tax payers if they maybe shut down community input and built more affordable housing and increased that supply! That state has the potential for 70 million residents if they put their development and density hat on. The Japan of the U.S..
Reality...
LA County has all the potential for an American Tokyo... just needs a rework. A Tokyo with Palm Trees. 6-10 floor structures replacing all of those single family homes with the support structures like schools, PD, expanded hospitals... some expanded transit, maybe Earthquake proof subways... and you got yourself a cool vision.
