It's a tax dodge.
I also remember reading stories years ago about CA/SV businesses that had offices up in Colorado as a back-up for when 'The Big One' hits.
And toll roads, etc...
In short, the money has to come from somewhere — if not from income tax then it will be from somewhere else.
The rate may be higher, but the total paid will probably be less.
CA/0.74%/$2839
TX/1.8%/$2275
You'll likely be paying close at best the equivalent of Silicon Valley housing.
