The Teachers Unions are responsible for teaching mathematics to students, not to the taxpayers. The teachers Unions are putting the students behind 31 other nations; at the same time they are putting 100% of the taxpayers behind the 8 ball. If there was a performance test for teachers, the performance of their students would be raised. If the Teachers Unions truly worked for fair pay for teachers, the taxpayers wouldn't be going broke. It is advisable for taxpayers to fund those schools that are not controlled by the Teachers Unions.
