um, have you been to sac? Given the choice, people (both founders of the companies & the best employees) would rather live in the bay area vs. sac. Hence the price difference. SF bay people are paying for things like: 20 min access to world class airport, one of the most human friendly climates on the planet, access to the capital of the internet & the people from around world building said internet, a stop on world tours of every major music act or performance, Ocean, Bay, coastal ranges, the ability to get to work, beach, entertainment without getting in a car, etc etc. I personally trust the wisdom of the crowd and find the best places on the planet to live/visit are often the most expensive: NYC, Copenhagen, Tokyo, Paris, Maui, Coastal Los Angeles, SF
