I agree on failed parents but not to the degree you do,I see a much broader picture ,I point to wages not as a red herring but as an undertaking of duty . The point your making is the parent has soul responsibility,The point I am making is in todays society this is not the whole case and media govs and schools all have influence over young adults as do their choice of friends...to suggest  a child who is maturing in todays world cannot decide for themselves a reaction to a situation is to suggest they are the parents robot,which is simply not the case and it undermines the childs own responsibility.

Experience tells me that whilst a parent can guide they cannot control so back to the environment a school offers ...should be exactly as you know it should ,if it isnt why is it not.

Parents have the responsibility you are pointing out but not the ultimate power to change a thing .

Teachers are not there to teach the kids manners but they surly know that teaching respect is part of the study and job ,now if it were a grain for grain this can go on forever,I do think parents and teachers should be a unity...They ask the parents frequently to help and make sure the kids do their homework...but hey thats the parents job ,cool please get rid of schools and we can teach are kids the curriculum respect and manners ...then if we have louts ...it the parents fault .
