The Bay Area’s public school system sustained another groin kick of aggressive generosity Tuesday when politically ambitious billionaire Meg Whitman bestowed $2.5 million on South Bay and Peninsula charter school programs. Apparently, the maid-firing former eBay exec didn’t spend all her money losing last year’s race for governor to Jerry Brown. The donation will go to Summit Public Schools, which established Tahoma and Rainier high schools in San Jose just this year. If the charter school’s name rings a bell, that’s because its first school in Redwood City was glamorously featured in the fire-alarm documentary Waiting for Superman. Whitman’s known for being a big fan of the film, which focuses on how the public education system is failing future generations. Summit’s founder and CEO, Diane Tavenner, as well San Jose Charter School Consortium director Alicia Gallegos Fambrini, certainly deserve a little merit pay for scoring the winning bid, but the cash infusion doesn’t bode well for the tattered public school system. San Jose Unified School District has done well to stave off massive cutbacks the last few years while other districts around the area were distributing pink slips. Whitman’s philanthropy, however, appears to be another charter schools powerplay. The charter schools somehow have become the charity darling of the ultrarich, with Netflix’s Reed Hastings and Facebook’s Mark Zuckerburg leading the way. We won’t hold our breath waiting for a press release about a Silicon Valley billionaire’s gift to a poor, underfunded school that can’t afford chalk and writing paper. At minimum, it would have to be something trendier, like a crowdsourced microloan.
