Parents aren’t barred, yet, from moving out of Kalifornica.
Actually, the California Legislature considered a bill awhile back that would CHARGE a tax for anyone or any business that moved out of California. Even if you died there & quit spending money there-—they would tax you.
I think the laws about Interstate Commerce prevented them from going forward with it, but they actually debated such a bill.
I cannot emphasize enough-—there are perfectly good places to live OUTSIDE of California that are cheaper—safer—and cleaner air than what you all are tolerating.
This kind of ‘textbook’ problem shows the degredation California has sunk to.
