There is a hefty sun burn tax in Texas. 100 degree weather for sometimes 30 straight days. May - Sept are all 90 degrees+ without fail. The winter is colder than the bay area.
I lived in both states and the weather in the Bay Area isn't enough to justify the heavy income tax, sales tax and cost of housing. It's great that it's in the 60s and 70s year round but with zero rain fall you got other cons making up for pros in that category. Sure Texas is hot and that is a downside but agreeing that the weather in the Bay Area is worth an insane amount of extra cash isn't correct.
If you have large housing needs (family/etc.) I can see that, but as a single person renting I didn't find the pricing difference large enough to be worth choosing Texas just for the housing savings. Paid about $700/mo to rent a 1-bd in Houston, vs $1100 to rent a nicer 1-bd in Santa Cruz, near the beach. Sure, that's almost $5k savings over a year in Houston, but you're not going to retire on an extra $5k. Well more like $4k savings overall once you take into account the extra electric bill I had in Houston, running the A/C for 7-8 months of the year.
