Wow. Okay, where do I even begin...
First of all, where did you get your information about why people want to be teachers? Have you been a full-time education student spending multiple years around the same teaching students? Have you worked with teachers day in and day own, getting to know some of their stories intimately well? I have. You know why? Because I am a former teacher. You want know why I'm "former" and not "current"? Post #65, Spiker. Post #65. You and I are not going to be able to have a rational discussion about this issue until you digest that post. Because many, many, many teachers, including more than one that I PERSONALLY KNOW, have had a virtually identical thought process about their careers. And you know what their final conclusion was? To hell with this. To hell with this school system who won't support me, to hell with these parents who berate me for just doing my job, to hell with the disruptive students that know they won't be disciplined, to hell with a society that makes all these problems out to be my fault. Trading in that for a dream job that has these things called "respect" and "excellent pay"? Why wouldn't we! And you wonder why schools have a problem keeping "good" teachers...
Another thing. That whole "make a difference in kids' lives" reason for teaching. Yep, been there done that. It's a great idea--until you find out just how hard that is to inherently do. But it gets worse--much worse. Teachers have to spend the overwhelming majority of their out-of-class time planning for lessons, grading papers, and dealing with parents, to name a few. And that's on top of the classroom conditions, where even if every single one of the students choose to behave well--which almost never happens in schools in impoverished neighborhoods--it's an incredibly stressful job where you are literally being closely watched every second. That kind of effort takes a monumental level of support. And you know what? A dire lack of that support is consistently cited as one of the top reasons for teacher turnover. Teachers feel taken for granted and basically hung out to dry. Anyone who flatly denies this (not you but some people in society) is an idiot.
Until you can choose to understand all this, and what I outlined in post #65, you will not have a CLUE why I am talking the way I am.
