Well, I suppose you're welcome, but this is one of those cases where the truth hurts. God bless your sister, et. al.
I was fortunate enough to find out by the end of my freshman year that there is no way I'd want to be a teacher.
But oh, they are SO important in kids' lives! For a great number of children, their teachers may be the only examples of civilized behavior that they ever see.
In my opinion, the U. S. has a small percentage of people who care enough to get involved and make efforts to improve the quality of life for everyone. I just read about a prime example: Shirley R. Watkins, undersecretary of our
Dep't. of Agriculture. While visiting an Indian reservation (speaking of gaps in society--shudder), she
noticed an inordinate number of homes with ramps instead of steps. She learned that many Indians were amputees, due to
complications from diabetes, which was exacerbated by the
federal government shipping unhealthful food. She saw to it
that all reservations got a good supply of fruits and vegetables after that.
There is a huge percantage of people in what I will term the
middle class, though I mean in more than the economic sense:
people who are the "average Joes", just doing the best they
can with what they have.
Then the scary part: an as-yet-fairly-small, but I'm afraid growing, percentage who have been so deprived all their lives of any kind of guidance or sustenance (mental and emotional, as well as physical) that they are essentially anarchists. These include all kinds of addicts, many of whom were born to addicted mothers, and who
truly do not have the capability in their brain for such things as self-control or respect for others.

Teachers in public schools have to try and deal with these
kids, who are well-nigh uncontrollable. So much classroom time has to be spent on discipline, I'm surprised as much learning occurs as there is. And heaven help the kids who
are just a little slow or learning-disabled: the teacher
sure won't have time to.
I certainly do not have a workable solution. I don't believe that throwing money at the problem will solve it. We need a national resurgence of higher standards and
expectations all around, as in when the vast majority of society noticeably frowns on and does something about
out-of-line behavior. Even something as simple as most
patrons in a restaurant glowering at the one unruly table
would help.
I have not been to every school in our county, but I've
talked with enough staff at many to have formed the opinion
that teachers themselves now expect very little of their
students, compared to even one generation ago. I think this
attitude is handed down to them from administrators, which is truly sad.
