theodp writes "Now that the Chicago teachers strike is over, the Tribune reports that Mayor Rahm Emanuel is pushing ahead with the aggressive expansion of charter schools, a key component in his effort to reform the city's public education system. The city aims to add 60 charter schools in the next five years with support it's sought from the Bill & Melinda Gates Foundation. In December, the Chicago Public Schools inked a Charter-District Collaboration Compact (full 'Confidential — Not for Distribution' pdf) to allow it to compete for $40+ million in Gates Foundation funding. Needless to say, Chicago Teachers Union President and ex-HS chemistry teacher Karen Lewis is not pleased ("This will have disastrous results and people need to rise up and refuse."). So, is this a fool-me-once-shame-on-you, fool-me-twice-shame-on-me moment, or are we better off letting well-meaning billionaires continue to have at it with public education?"
