Earlier quoted context omitted.
Then companies better start paying more. This is how supply and demand works. If $130k only gets you incompetents, then it's time to start offering $200k, or whatever the magic number is. Remember: Any time you hear an employer whining about "lack of qualified candidates" be sure to mentally append "...at the rate we want to pay."
And that's a big deal. But if the cost of an employee is > their value, you get massive off-shoring. That's the danger, and as an Australian the opportunity, of Bay Area pricing being so crazy. If the Bay Area wants to keep its advantage - in a world where Alibaba is the lead IPO of the last 5 years - it needs to remain competitive in all ways. Rome wasn't built in a day, but it fell in one.
It may be that the cost to attract talent to the Bay area is now too high for all but the most profitable businesses. I have no idea if this is true or not but conceptually the giant payrolls needed may finally be overwhelming the benefits of locating a company in the area.
