Arne Duncan, the brightest and most dedicated schools leader Chicago has had in memory, wants Chicago to be a Mecca where entrepreneurship can flourish. In this article, the authors contend that private management of Chicago schools is a long way from Mecca. There is no evidence or educational research whatsoever to show that privately run charters can produce better results. They urge a renaissance in schools based on expanding and not selling off the public space. This involves mobilizing communities and engaging and unleashing the talent and wisdom of teachers. At his best, Duncan has upheld this direction. In this contested space, this conflict over principles and fundamentals, they hope that Duncan finds a way to bring the resources and support of his business partners into play while preserving and transforming public schools and respecting the rights and the power of engagement of teachers and communities.
