Everything here is significantly more expensive than the rest of the country, with the possible exception of the greater NY area, including but not limited to: sales tax, income tax, cost of goods, and housing. It’s pretty anti-internal combustion engine here, and that is evident. Tech jobs pay well, but you could have a comparable standard of living elsewhere for far less.
There are speed and traffic cameras everywhere, traffic is bad, and things are crowded. Public education has fallen significantly in the rankings and kids from CA can’t get into local schools or want to get out of the state.
Yes, weather is and has always been great but you are paying a hefty premium for that. So, if you like it, good for you, but this isn’t a model for other states or the US economy because the revenue derived from Silicon Valley makes the uber left tax and spend possible.
