There’s are some grounds for arguing the effects of White Flight, along the lines you have. Your area seems more Leftist. I would still submit that most of the folks who did flee Southern California, were home owner worker bees rather than folks benefiting from state largess. We’ve also seen a lot of businesses relocated outside the state. Non-union workers are more likely to be at least independents rather than avowed Leftists.
What saddens me, is the populace that once could support a man like Reagan, is now unable to find the brain cells needed to repel an idiot like Jerry Brown.
If you look at the numbers of Californians who have left, you’ll note that it pretty much mirrors the amount we are now losing in-state elections by.
California now has somewhere in the neighborhood of 35 million residents. If it had even 5 million middle class whites in the traditional areas they used to live in, you’d see California right itself in five to ten years.
Would that this could happen soon! I've seen so many good folks leave the state due to lack of good jobs, as hundreds of thousands of small manufacturing businesses fled the state.
I remember so well that many of the same problem existed when Reagan became Governor here, and we experienced a huge return of manufacturing and other small business that hired tens of thousands. I remember too, under Reagan, we had a massive expansion of home building, and homes were CHEAP (as compared to current prices.)
