Facebook feels confident it can address San Francisco's high-priced housing problem — and chief policy officer Elliot Schrage says it has to "if we're going to remain a company in Silicon Valley for the long term."

"Our position is that Silicon Valley has been this extraordinary engine of economic opportunity and if we can't solve the housing and transportation issues, Silicon Valley won't be Silicon Valley," Schrage said at the company's annual shareholders meeting. "These companies like ours will expand elsewhere. So we feel a real sense of urgency around that."
