sdr: nice dodge. You can’t face the fact that Californians (and San Diegans) are leaving for a long list of reasons, despite your great weather. BTW, the great SD weather also makes San Diego a great draw to your homeless population.
And yes, it is documented those leaving are on average higher income people. The very factors you mention, like land costs, combined with utility costs, expensive and poor schools, etc. are prompting the exodus. Regarding the latter, a study just compared educational results by state in the return to post-covid school test scores. Because CA locked down for so long, they fared worse in national test scores than Mississippi. So the poor whites and poor blacks of the deep south outperformed CA students (UT scored 3rd in the nation).
And the trend seems to be accelerating as more people move based on the lower cost of living. Want to escape the nearly highest state income taxes in the nation? Move to income-tax free Nevada, Florida, or Texas, or low-taxed AZ or UT. You’ll get twice the house for half as much money. You are correct to point out they are building like crazy here and people are flooding in. When we meet new people here, we always ask “Where are you from?” Usually it is coastal California.
Have fun paying for full medical care for all illegals, and for huge reparations for Blacks (who will start moving to CA in droves if reparations become law). As your favorite politician (I’m guessing) might say “C’mon man”.
