For anyone interested in this issue in the US, there's an excellent new book out called A Wolf at the Schoolhouse Door, by Jack Schneider and Jennifer Berkshire. It traces the push and pull between the promise of quality education for the masses through public education, and the attempt to extract as much profit as possible from schools that's been going on for a very long time.

They dispel many myths that persist about public education, and connect current privatization pushes to decades-long attempts to undermine public education.
