"In the last three years, profits at the seven largest companies in Silicon Valley by market value have increased by an average of more than 500 percent while Santa Clara County employment has declined to 767,600, from 787,200. During the previous economic recovery, between 1995 and 1997, the county, which is the heart of Silicon Valley, added more than 82,800 jobs.
Changes in technology and business strategy are raising fundamental questions about the future of the valley, the nation's high technology heartland. In part, the change is driven by the very automation that Silicon Valley has largely made possible, allowing companies to create more value with fewer workers."
