Last week, protestors in San Francisco blocked the path of commuter buses shuttling workers to Silicon Valley. Claiming the tech sector is destroying their city, the demonstrators piled electric scooters in front of coaches enroute to Google, Apple and other hi-tech companies.

Even though those companies have brought enormous success and wealth to San Francisco, prices have soared, particularly for property. Homelessness has also skyrocketed and commutes have been lengthened by the lack of affordable housing across the city. The growing levels of dissatisfaction in the Bay Area can be seen by the results of a new survey.

Conducted by the Bay Area Council advocacy group, it found that 46 percent of voters plan to move away. That's a noticeable increase on 2016 when 34 percent of people agreed they'd move out due to the situation. Even though the Bay Area has full employment, only a quarter of those polled said that the economy is going in the right direction.
