Any parent that calls themselves a parent should desperately want to impart all the knowledge they possibly can into their child. A real parent wants their child to be better than they were.
Additionally every American should want every child to be better, stronger, smarter, tougher, more responsible, more capable, more ambitious and more self reliant so the country itself can be all those things.
My parents, my grandparents, my uncle, everyone growing up tried to reach me what they knew. I was made to do my homework, do chores, have manners, read books, watch and listen to a variety of music and movies, take swim lessons, learn to cook somewhat, hunt and fish, fix things, learn about money, be able to do math, and so on. My dad took time to sit and watch mr wizard with me so I would learn simple physics and science when it was on tv because it wasn't his strong point.
If you don't want to help your child, or if you don't other parents/teachers to help children be the best they can be then you're doing a disservice to that child and in essence to America itself.
