The fact they are passive is why the reformist jerks have made so much progress in the destruction of public education in the United States.
The problem with Greene’s “logic” is that “going along to get along” doesn’t get anything accomplished in our society. People who have made a difference for the better in this country are willing to take risks, even risk their lives, for the greater good. Teachers have long been too passive because of the fear of being fired by administrators. However, that is a different issue.
The teaching profession and public education are literally on the ropes. Sitting around doing nothing but going along with the flow accomplishes nothing and makes the enemies of democracy even MORE emboldened.
