It's a Fact: Teachers Are Typically the Dregs
(Disclaimer: I do not believe that the above article is true of all teachers - we have several Freepers who are good teachers)
Then you have already contradicted yourself. If you think competence is essential in a teacher, what makes you think that you are going to get it from the current product of teachers' colleges? Those people are hardly literate. Even if raising salaries to attract better students would work, what do you do to rid the system of its huge number of existing incompetents who all have seniority?
It's never worked. We are fifty years beyond Why Johnny Can't Read, we are twenty years beyond A Nation at Risk, we keep adding money, and it's getting worse.
Idiot, stay away from my kids.
