>>Stanford economist Caroline Hoxby also has studied how teacher unions affect education. While there is evidence that teacher unions have a pretty big positive impact on how much is spent on public schools, there is either no impact or a negative impact on student performance, she said.
In other words, they unnecessarily drive up costs without providing any benefit to the students.
Government employee unions should be outlawed.
Letsput it another way. Teacher union leaders are more interested in getting money for the public schools than for getting more money for teachers. Furthermore, the NEA especially is not democratically governed. Like many another union, it draws all power into the head and cultivates group think.
