Have you ever wondered why the rich and powerful seem to have so many opinions about public education, especially when neither they nor their children have attended public schools?This is the first of a two-part series exploring how the rich and powerful are cashing out on public education. Today, we’re looking at the big picture: the historical, decades-long agenda by wealthy donors and corporate interests to privatize schools, weaken unions, and limit what educators can teach. Our guest is Lisa Graves, founder and Executive Director of True North Research.
