To me, bad teaching and burnout is entire the result of teacher's unions and bad parents. And neither of those things seem to ever be blamed or addressed.
IMHO---this is a huge concern....and a much bigger issue for America today than the union...
My oldest daughter and wife work in public school systems...and if you heard some of absolutely sickening and sad stories about the physical/emotional condition of children and how they are sent to school daily, and then the total non-commitment, lack of involvement, and absolute disregard for their children's well being and education...it would literally break your hearts, and make you very, very concerned for the future of our nation.
