 At the time of the strike, one in five LAUSD students attended a charter school, siphoning an estimated $600 million dollars a year from the financially strapped school system, according to UTLA  which called for a moratorium on charter school authorizations, an end to school privatization and robust funding for public education.Los Angeles had more charter school students than any other school district, in part because anti-union interests and billionaires, such as the Walton heirs to the Walmart fortune and former New York Mayor Michael Bloomberg, spent hundreds of thousands of dollars to elect a pro-charter majority on the seven-member school board.Fact-finding and mediation continued for several months, while teachers, counselors, parents and other community members rallied in downtown, Los Angeles, marching through an echoing 3rd Street tunnel, right up to the entrance of the Broad Museum, built by real estate magnate Eli Broad, who a few years earlier had conceived a plan to turn half of LAUSD into charter schools.
