> Bay Area companies hire in the Bay Area, for the same reason companies are founded in the Bay Area to begin with: because most of the VCs in the US live in the Bay Area.
You're putting the cart before the horse. Investors live all over the place, and large funds have offices in markets where there is a signifcant number of possible high growth companies to invest in. And they'll invest where they don't have an office and always have.
The reason why so many investors are in silicon valley and san francisco is because of the companies. And the companies are here because of the environment. I've worked around the world but the reason I love working in the valley (specifically the peninsula) and not elsewhere, not even SF, is because of the extreme density of people, resources, markets, and just the sheer intensity of the place. I hire from all over the world, but really, just getting shit done is so much easier around here.
Ignore the bros. Those assholes get the press 'coz they're interesting to write about. I'm talking about nerds in true tech businesses like hardware, software, mechanical systems, pharma.
It's not for everyone, and even people who would like it may choose elsewhere for other reasons. Those decisions are all legit too.
