Is this just because people are moving out of California to other states? If so, maybe California needs to change its brand of politics to have a higher retention rate.
A bunch of people I know have moved out of the State. Mostly because housing here is completely unaffordable for an average couple. And it is doable in other states.
This is not just California. I live in Washington and wouldn't have been able to afford my house if I was buying today. Inflation + interest rates + price jumps.
