Say I want to work for Google, want no more than 15 minutes commute, and want to live in a house of ~2400 sq.f (which I live in right now).
How much would it cost me per month (both net and gross, considering that I have to pay taxes prior to paying my rent)?
Up to 15 minutes covers an area of 400 square miles if you're driving from a commuter suburb to an office building and take the freeway most of the way. If either the source or the destination involves a 'proper' city with any kind of population density, that range shrinks considerably.
There's life outside of Palo Alto and SoMa.
