This is my experience as well. OP is parroting a common talking point from the groups that want to privatize education.

OP is sharing their experience, and you are sharing yours. neither experience is universal, and it has nothing to do with wanting to privatize education. rather it is a call for reform of the school system. (all public schools should adopt the montessori method in my opinion for example. it's not expensive. it takes just one year of training for teachers)
