One reason there are so many young teachers who can't land contract jobs (in Ontario, anyway) is because the school boards save a lot of money by stringing them along, year after year, as "long term occasional" teachers.  It is a terrible policy, and one that will backfire very badly before long.  Trust me, there aren't many teachers who hang in past their due date.  At 70, and making 170,000 a year, this guy is obviously doing something well outside of the public school system; even Superintendents don't make that kind of money, and none would be allowed to scale back.
