In my work , this extremely dangerous and offensive idea continually shifts to the surface--"we are here to save the children," or "we are the only place that can save children." Or some of the form of the phrase. Many people attracted to the field of education are attracted because they have a desire to do good in the world and make a difference. At the surface there isn't anything wrong with this idea. Doing good, and making a difference on their face are ok mantras or mottos. They become problematic when you begin to see yourself as the second-coming. The only real reason to teach and be part of education is because you, yourself love learning and sharing knowledge. It is not the place to become superman. (Although at times the amount of work can require superhuman endurance.)
Honestly there are only certain times in life when you can truly save another human being---when a person is literally drowning and you pull them out of the water, when a person is literally trapped in a burning building and you run in to save him, or some other real life- and-death situation. Otherwise, each person is the key to making his/her life better. Knowledge and learning are intimate and personal.
I bring this up because one of the fundamental problems in education is well meaning people who begin to mistakenly believe that they are 1) the only source of knowledge 2) the only chance a student has 3) the only teacher a student will have and 4) that they must feel sorry for their students. If this list describes your mantra get out and get help.
Belief is at the core of actions. People who subscribe to the saving people mantra also subscribe to the idea of lowering standards. Of course they don't call it that. They tell you they believe in high standards and rigor but their actions belie their true underlying belief of "these kids can't do it". They lower standards in every conceivable way. They lower the bar for attendance, timeliness, quality of work, respect even the mundane common human standards of politeness and courtesy.
If you believe that you are a savior--seek psychiatric counseling. If you want to save people for a living become an EMT or firefighter. If you love learning--teach.
