Why are you holding teachers to a standard of social accountability that you would not ask for in anyone else? "How dare those uppity teachers band together to secure an income. They should teach for the love of it alone!"
Don't delude yourself into believing that this is about removing bad teachers. Nothing in the proposals is doing anything to improve education. It's just trying to kill unions as if that a magic fix. It's the same as TMM's belief that giving more authority to state governments will magically fix all financial problems.
It's illegal but it's happening.
Non-sequiturs aside, what evidence do you have that these are in fact their goals. You are saying that their goal is to hire teachers that can't be hired elsewhere. That's a pretty bold statement. So I assumed that you must have some evidence to back it up.
If there are any that do not at some level believe this to be true then the best you can say is that this is what they achieve.
