you don't have to move that far to escape all that. Plenty of areas an hour away from San Jose that are nice and a lot cheaper (still more expensive than Texas or Florida, sure).
Depending on if you need to change jobs and the family situation sometimes it's just as much effort to move states than move a few hours away.
If you have the opportunity it's good to look at the entire country, sometimes even the world (though for tech the US is by far the best option) for the best value.
Even moving 2 miles away will result in better quality of life. Downtown San Jose has the some of the highest crime rates and largest homeless encampments in the city, and the rent in other parts of the city is not a lot higher.
But if I'm moving an hour away, why not move farther? I was born, raised and have lived 31 out of 34 years in California and I just can't fathom why anyone would choose to live here anymore. I bought a house in Southern Oregon 4 years ago and moved up here full time a year ago thanks to the pandemic. I really hope I never have to move back.
Southern Oregon is a far cry from Texas and Florida as the top comment mentions. I don't see how either of those states would factor in especially for my partner who champions women's and LGBTQ+ rights...
No need to drive even an hour. Downtown San Jose is certainly a hellhole (I worked downtown on Santa Clara St. for a while) but just a few minutes away there are very nice suburbs like Campbell, Willow Glen etc.
