I love California, born and raised here. There are at least 4 Californias: Southern, Central, Bay Area, Inland...maybe more. The variety is part of the charm with the highest and lowest points in the lower continental US just ~100 miles apart. The granite domes/slabs of the Sierras, along with sapphire blue skies, are stunning. We have the tallest, the largest, and the oldest non-clone trees in the world. I don't think most people realize how interesting the micro climates are: I see Oak/chaparral, pine, redwood/ferns, coastal bluffs, sandy beaches, and more all within the span of a single bike ride. And the weather can shift dramatically within just a few miles - this is part of the reason it's such a big wine producing region.
As much as we love it here, we're likely relocating in the near year or so. This is not something we take lightly and there are many complex reasons. To over simplify a bit, the extreme cost of living is a big factor. Cost of housing for sure, but this also has a ripple effect on cost of food and services, making pretty much everything else more expensive. The urban areas have mostly failed to plan for growth, opting instead for a no-growth philosophy over the last 3-4 decades. The idea was to preserve our way of life, our little piece of paradise, and we assumed "if you don't build it, they won't come." Well, it didn't work and we ended up with a lot of urban sprawl, insane prices for mediocre housing, and a hollowing out of the middle class as houses are purchased by wealthy tech employees and service workers cram into garages and out buildings.
Those big companies listed up-thread: Has no one else notice that these are *all* tech? About half of the state's income tax revenue comes from the top 1% of earners, which is now very tech heavy. I've lived here over 40 years now, and during that time the state has oscillated between feast and famine, which has gotten worse as we increasingly rely on taxing the rich. In other words, the tax burden is not spread widly enough. There are major unfunded liabilities w.r.t. pension obligations that are starting to come due. My city of 65k people, within commute distance of SV, is running a deficit of $5M in an economy that is absolutely booming. Every place is going to have some mix of these types of problems, but it's particularly bad in CA. Faced with the prospect of cutting pensions or raising taxes, I expect Prop 13 will be gutted - which is probably the right thing to do. The state is very dependent on tech at this point, but tech is extremely mobile, especially software development which can be done almost anywhere. I don't think SV is going to go bust overnight or anytime soon, but tech companies are already shifting hiring outside of the area because they are having difficulty recruiting and retaining people in the Bay Area due to the extreme cost of living. It will be a long slow drain, which may already be happening to a degree, and no one will notice until it's a problem.
Many urban areas in CA have major issues with crime and sanitation. I go for walks with my kids and we play spot the drug needles (I want them to know what to watch out for) and dodge the human poop on the sidewalks. I'm not a super fussy or clean person, but even I find it pretty gross.
So we love it here, but there are limits. At some point the sunshine tax is too high. The places we're looking would save us 500k-700k on housing, plus lower overall costs in general. With that difference invested we could afford to visit CA when we felt like taking in what it has to offer, while at the same time enjoying clean parks and maintained infrastructure in a different state.
