Why did Matt Kramer step down as co-director of Teach for Anerica? He was making $400,000 a year. On the other hand, he had never taught.

Gary Rubinstein, TFA 1991, is one of the closest watchers of the organization. He makes some educated guesses. He predicts that the other co-director won’t be around long.

He wouldn’t be surprised if Wendy Kopp returns to salvage the organization, which pulls in a cool $300 million a year.
