It is simple problem with a simple solution.
Bad teachers hurt our kids!
Good teachers pay their union dues to ensure the bad teachers can never be fired.
Acknowledge the teacher's unions are hurting kids and slowly destroying our country and then:
Then, we end the unions (including firing every goon teacher that pays dues - they can re-apply for teaching jobs and compete for a change) and then vote out the low life politicians who sell OUR souls for the union goon campaign contributions and GOTV efforts.
