What makes teaching noble?

Many people think that teaching is a lowly profession and it is for the second rate who cannot take up other degrees such as engineering, law or medicine. However, time is evolving and many countries such as USA and UK have made the requirements for entering the college of education tougher and governments have also made big steps in making the teaching profession more attractive including raising salary for teachers. So, what makes it noble now? Teaching students life-long skills is in itself noble. Of course, we don't have to discount the fact that teachers make engineers, lawyers, doctors, scientists and all sorts of professions on earth. Without teachers, there would be no succeeding professions and even skilled workers.

I really admire teachers who handle the nursery and kindergarten. They are commendable as they don't only act as teachers but also as nannies or parents to their pupils. One of my friends teaching in the nursery complained of doing even the dirtiest job of changing the nappies of children if they poop or pee. Then she has to teach them how to speak, write, read, sing as well as how to eat, behave or how to be polite. Many teachers are entrusted by parents their very young children at the care of these nurseries so the job of teachers makes it very crucial. They are expected to form not only young children's literacy but also their character. Whew! Isn't this nobility when teachers shape the future of the generations?

In the international conference I attended recently, the participants were reminded of the role of humanities and social sciences in making responsible, ethical and caring for humanity engineers. If we just allow students to develop just their brains but devoid of feelings or care for humanity, we develop monsters or robots. So, isn't it too demanding for educators or teachers to do all these things?

With too busy parents in this highly competitive world either making both ends meet or just satisfying their ever increasing  and endless needs and desires for earthly fame and pleasures, and who just  rely on teachers to develop their children's life long skills, values, morality and ethical consciousness on teachers, what would the world be like without educators? So, aren't teachers really noble?
