No, the parents are NOT the bosses, no matter what you might think. Nor should they be. Most parents have ZERO knowledge or understanding where childhood education is concerned. Parents are given the incredible benefit of a public education. Billions of people around the world would love to have that option. It’s the parents and their children who are given a fantastic opportunity, not the teachers. Our education system is why so many people want to come to this country.
If you think schools are bad now, it would be far, far worse if they followed your suggestions.
