It mostly has to do with the Teachers Union, I remember in middle school the teachers picketed for more money. I thought it was pretty lame, they even taught slower and made class unproductive(although as a kid I loved it, in hindsight it's just disgusting for a professional to do that) to get what they want. I am supportive of Unions, as long as they don't act like children.*cough*
