Californias major problem is who pays taxes here. In a State of 40 million people, only 150,000 pay the bulk of the taxes, and those 150,000 are the ones who are leaving. If the Marxists who run Silicon Valley decide to pull up stakes, the place will implode. Which I hope happens, because financial collapse is the only remedy.
Just buy a house in another low tax state then rent you California dwelling back to yourself. Then you wouldn’t have to physically leave.
