I see a problem or two... in my state, and most others that I'm aware, each teacher has an individual contract with the school system. Therefore any changes along this line... the union would require a separate hearing/lawsuit for each teacher/employee. Without getting indepth... this has been done many times in the past when attempts are made by school administration to re-constitute schools (in otherwords fire all tenured teachers in order to get rid of one or two who are considered incompentent by administration and then re-hire the others). In my area we are talking about more than 5,000 lawsuits (which requires a lawyer to represent the system at 3 to 8 hours for each case... depending on how long the union lawyer wants to drag it out). This would bankrupt any school system in North America... many times over.
...then eliminating public education as a right.
Now you've trespassed into the Federal domain. No way will this ever happen. Even if it were proposed by a congressman the NEA and state unions would pump millions of $$$ to see that this bill never saw the light of day.
Any changes that will improve or fix what is broken must be at the social/cultural level. I see church schools and home schooling as the only fix for the many problems within public education. As long as 'public' education is not valued by those who need it the most... those changes will never be made. Also, there is no motivation by congress critters to take on the most powerful labor union in North America... without a social revolt.
Unions are like cement... they have 'mixed' education up with labor being the main concern to the point where we are forever 'set' with a failed "public" school system.
Only the very best would hang around, however they amount of pay is needed to compensate for lack of benifits and security, it would also help pull talent from industry.The Union Pimps (my wife and I pay $130 a month in Union dues, she's a teacher) can go rot.
