What a condescending -itch. My husband works for one of those "Silicon Valley-based tech companies" right here in the center of the country - Oklahoma City. They may lease office space, but it's cheap rent and because of the internet, most everyone can work from home anyway. The cost of living is cheaper and they can get away with paying lower salaries that are still excellent for this part of the country.
If we lived in CA, he'd be making 3 times his current salary but we'd pay 4 times for everything. California's a beautiful state, but so is Oklahoma, and she can keep all that attitude out there, thank you.
