Troy is right, the school is the primary educator. We homeschool so we are the school, but I was in education for 20 years and I knew that teaching Beowulf, Catcher In The Rye or Hamlet was my duty and I loved the entire process. I even brought my college level books to class so they could see the difference in their text and my text. This is what good teachers do... but as Troy said, a lot of teachers are there because the pay is consistent and that is really about it.
The parent can be supportive, but I don't expect a parent to be able to share the burden of education. I only expect them to support. I have an interesting story. I taught at a school in San Diego in the poorest part of the city. The school was primarily immigrant an second language students from all over the world. We had over 100 dialects spoken at the school. Those students had fewer resources and had the extra burden of learning the language, yet they turned out to be some of the brightest and most successful students I worked with in my 20 years. The Black students are doing well from that school as well although they lived in an area called the 4 corners of death where a Crip and a Blood territory intersected and most of their fathers were absent. I leave that school and come to Memphis which is a white and black city and the black kids here are struggling. They face poverty, but not nearly at the same level as kids in San Diego where the poverty line is 75000 and the median household costs half a million. These kids can literally have parents make a living working at Mc Donalds in Memphis because the cost of living is so low, so explain to me why they aren't succeeding in the same way the kids in San Diego are succeeding?
It's not that the schools can't teach because of taught in those schools as well. It is not the system that is failing kids. Even a shitty school can teach kids something. Education is about support and as much as it pains me to say it, Black parents (I would say 30%) just aren't supportive when it comes to books and improving themselves. That 30% that screws up the schools is considerable enough to screw up everybody. It just amazes me that the "poor" schools in a city where the cost of living is ridiculous can perform so much better than kids in a comparable situation in another city.
Oh, on Ben Carson... I left that because why discuss something that doesn't matter?
