I get so tired of hearing this. My husband was a teacher then an administrator. After 36 years teaching and a Masters Degree he made it to $40,000 before retiring. He NEVER had 3 months off because he had to teach summer school in order to make ends meet for our family.
As far as a teacher never losing their job, that is not so as when my husband was a vice-principle he helped in getting a teacher fired. Yes it is difficult, but it can be done.
That number would be a lot higher currently where I live and no administrator would make less than double that in this area.
I know several teachers, including my sister-in-law, who topped out, after 25+ years in a metropolitan system, at well over double the reported salary that you mentioned .
The retired ones are all drawing lush pensions from school districts that can barely afford annual operating expenses. One thing the districts do have money for is plenty of administrators who campaign incessantly for various tax increases.
"It's for the children"...
My niece and her husband are 30 years old and each makes 70,000 dollars already after just a few years of teaching. It also probably depends where you teach as to how high your salary is. They are in Warwick, NY high school, math teachers and they coach, he football, her cheerleaders.
