Alastair Gee writes via The Guardian about Palo Alto's problem with homeless children. Palo Alto is one of the most expensive cities in the United States, yet "slightly more than one-third of students (1,147 children) are defined as homeless here, mostly sharing homes with other families because their parents cannot afford one of their own, and also living in RVs and shelters." From the report: The circumstances of the crisis are striking. Little more than a strip of asphalt separates East Palo Alto from tony Palo Alto, with its startups, venture capitalists, Craftsman homes and Whole Foods. East Palo Alto has traditionally been a center for African American and Latino communities. Its suburban houses are clustered on flat land by the bay, sometimes with no sidewalks and few trees, but residents say the town boasts a strong sense of cohesion. Yet as in the rest of Silicon Valley, the technology economy is drawing new inhabitants and businesses -- the Facebook headquarters is within Ravenswood's catchment area -- and contributing to dislocation as well as the tax base. "Now you have Caucasians moving back into the community, you have Facebookers and Googlers and Yahooers," said Pastor Paul Bains, a local leader. "That's what's driven the cost back up. Before, houses were rarely over $500,000. And now, can you find one under $750,000? You probably could, but it's a rare find." Several homeless families whose children attend local schools told the Guardian that they had considered moving to cheaper real estate markets, such as the agricultural Central Valley, but there were no jobs there. One man shares a single room with three children, in a house where three other families each have a room. Another woman lives with her partner and five children in a converted garage. Even teachers are not immune to such difficulties. Ten of the staff who work on early education programs -- one-third of the total -- commute two or more hours each way a day because they cannot find housing they can afford.
