I think teachers are the best for the nation. Teachers can help grow self esteem and confidence to learn. They also teach students the foundations of knowledge that we need to function in society like critical thinking and history.
You are right, teaching is not my discipline for me to support that teachers is the father's of any nation because when looking at this three angles of fields Teachers, Doctors and lawyers, theirs are all important but teachers are the most important because teachers gives rise to others, without teacher passing the knowledge to doctors and lawyers they won't have known the part a doctor or lawyer will play for the nation, so i agreed that teachers is foundation's of knowledge
