Hi-tech has been and is moving out of California. Companys can’t find people that know what they are doing.
The economic burden of Kalifornia doing what Kalifornia does is not a burden that a high-tech company should have any interest in taking on.
Kalifornia refuses to discipline itself fiscally at a time when the economy is booming. The state is attempting to take over the solutions to every conceivable problem of mankind, from mandating medical insurance, to solving the non-existant human-caused global warming, to dictating to people in the Tahoe basin that they can't clear the natural vegetation around their homes.
The costs of all of these things, of necessity, fall on Kalifornians. As the productivity of Kalifornians falls, the standard of living must fall also.
Kalifornia has purposely become a haven for millions of under-educated illegals. The medical problems and education burden for these millions has been placed on the backs of the productive. Those who can most easily leave, will do so. The productive who consider moving to Kalifornia will opt not to do so.
