Maybe that is what they want? People coming to Cali to burn their passion and youth, fueling the economy. Then they get a bit of savings if they rent and live like crap for a few years and jump companies to somewhere more affordable.

Because honestly, unless you hit it big somehow or already have a house in SF before, I don't see how an average salaried worker can afford a family home there. Settle down and making a new family is just near impossible.
