Thanks for this. It's good to see thoughtful writing on Chicago's education mess.
"But Chicago Public Schools (CPS) policies are not really about Duncan or his successor. The biggest threat to finally achieving equitable and quality education in Chicago's low-income African American and Latino/a schools is not the individual who carries out the policy but a system of mayoral control and corporate power that locks out democracy."
That criticism pretty much sums up almost all Chicago politics, not just the realm of public education.
