It's called the diversity tax. It can be steep.Very true.
Demographics of California are changing. Lots of people taking their $$ and going places where it spends better.
Though it's not entirely because of taxes. It's partially because their California home makes them a millionaire and it is financially logical to cash out when they retire.
Plus there are hidden taxes. E.g. in most California urban areas, you need garage parking, or secure off-street parking.
Otherwise your car will end up like the truck full of sea-food that got lost outside one of the housing projects at Mission & 24th in SF in the early 90's.
Truck driver had his cargo stolen. Then he and his wife ended up in the ER, and dead.
I figure all the car break-ins is sort of like a tax.
