I don't expect the public school system to teach my children anything. Hence why they won't be attending. Most of the schools I attended growing up were completely useless. Filthy, full of drugs and gangs. Sadly I even listened to some of my teachers more than I did my own parents (indoctrination) which I now see lead me down the wrong path. I don't expect the public school to teach my kids any kind of career skills…
I was that kid. I went to the "best" high school in all the surrounding cities. It was a mess, sub-pair on every academic, legal, and social level. Teachers taking bribes, drugs, fights, teachers that didn't know their subjects well enough (I helped teach one class).
I dropped out and went to college.
