I would opine that this discussion has lasted much longer than anticipated, but recent posts have ventured into an area I discussed in another thread.
That is the propensity for teachers, whether on the high school or college level to pontificate on subjects unrelated to their given expertise, and somehow consider themselves more qualified that John Q. in doing so !

Let us go back to "square one"... It is highly likely that everyone here has spent from 10 to 18 years in the classroom, at least as students, thus having a reasonable working knowledge of how it works. Most teachers have 16 years in the classroom when they start their working life..
Public education is one field of endeavor, however there are thousands of others. Engineering, mechanics, retailing, social sciences, agriculture, military, public service, etc., etc., etc..... Fields many teachers may have no experience in.
Often these people also have many hours teaching, whether in a work, church, scouts, fire company, trade or other related fields and thus are not strangers to the task, so obviously neither teachers nor the rest of us should be given special credence beyond our field unless we have demonstrated a special acuity for it.
Make sense ?
