This New Yorker article is an amazing bit of reporting about the completely absurd system we now have in place that protects teachers' jobs no matter what they do, who they hurt, or how ineffective they are. How many more millions of dollars will we spend on "teachers" who have been removed from the classroom-- and aren't allowed to return?
