Boomer... the problem with salvaging the institution is that, even when it was running well, it had serious problems. Not "we're teaching the wrong values" problems, but "we aren't teaching well."
But let me interrupt myself to say that there are quite a few educators in my family. All of my grandparents were teachers, several of my aunts and uncles are teachers, etc... from grade school on up, from the classroom to the principle's office, my family has been involved in the front lines of public education for a long time.
Public schools are miserable places for children. They stifle creativity, push conformity, and discourage excellence. This isn't entirely the teacher's, or the school's, fault. The students themselves are a major disruption to learning. Poor students are teased and harassed by other students instead of being given extra attention. Excellent students? They too are harassed and pushed to conform by less capable students. The teachers deserve a lot of the blame as well of course. Many teachers find a capable student to be very intimidating. A teacher of average intellect, spreading their attention over 15-30 students, is simply not going to be able to interpret what is going on when presented with a bright and capable kid.
And you know what? A lot more kids start out bright and capable than end up that way.
Public schooling as it exists today is flawed at its core. Home schooling is better because it allows individual students to set their own pace and (usually) puts them in a 1:1 relationship with an interested teacher (the parent). The flaw there is that the parent may not be all that good a teacher. They may not understand the material or may not be able to convey their understanding. On the plus side, those bad teachers are going to impact fewer lives. A bad public school teacher is going to interfere with the development of maybe 1000 kids... a bad homeschool teacher may mess up one or two kids.
The only people who do well in public schools are the middle of the road students... and even they don't do as well as they would in a better setting.
That's even before you consider the social influence issue we gun owners are learning about to our sorrow. Schools are a natural destination for people who want to push a social agenda... including anti-gun agendas. By handing off the education of your children to strangers they basically cease to be your children in some very important ways.
You may have guessed I'm not a fan.
