Is the problem with public education really that older teachers are incompetent but are protected by tenure? Should elementary school and grammar school teachers not be paid extra to get masters' degrees? Or are both arguments simply efforts to lower the cost of public education by practicing age discrimination, firing older teachers and hiring younger, cheaper teacher?
Michael in Chicago has a really good blog post on these and other questions about public education that the media does not seem to want to bother the public with.
I strongly recommend reading his blog and the intelligent comments. Then ask yourself why this information is not part of the so-called dialog on the education system?
