Fears that heavy housing costs could undercut Silicon Valley and the Bay Area’s economy have grown steadily in recent years as gains in wages have been outstripped by soaring rents and home prices.

Now a poll of 1,568 registered voters in the region done on behalf of the Silicon Valley Leadership Group and Bay Area News Group paints one of the starkest pictures yet of public dissatisfaction.

Those polled were nine times as likely to say life in the Bay Area and Silicon Valley had gotten worse over the past five years than to say it had gotten better. Forty-four percent of respondents said they wanted to move out of the region because of housing costs, bad traffic and declining quality of life; 6 percent intended to leave in the next year. African-Americans and Latinos were those most likely to want to move elsewhere.

But even 64 percent of homeowners – normally much more content than others in surveys on life satisfaction – said their lives had gotten worse.

The results produced yet another warning from the Silicon Valley Leadership Group, which has cautioned for years that the region will struggle to attract workers for tech and blue-collar jobs alike unless housing costs stop spiraling upward. The group’s CEO, Carl Guardino, told the San Jose Mercury-News that “not working at our weaknesses will come at our own peril.”
