Why do many middle school teachers say never to be a teacher in the future?

Being a teacher is very stressful, and you have to bear the pressure from all sides. Generally speaking, he can't earn any money, and it's not easy for him to ask for leave. He will worry about his job title, marriage and buying a house, and he will not be able to spend more time with his family and children in the future. In middle age, he has white hair or baldness. Moreover, teachers want their students to have greater ability and better development, instead of being confined to campus all their lives. He doesn't want his students to be great. In such a social environment with material conditions as the premise, he just wants them to live better and more freely in the future. Civil servants, on the other hand, have good welfare and stability. They are still young and have opportunities, so they will be expected to take the civil service exam. A person is the same, a person has dreams, and different people are suitable for different jobs. Don't judge a thing without personal experience. No matter what others say, the choice is ultimately in the hands of the students themselves. If no one is a teacher in the future, it is unimaginable, so we should give teachers more respect and understanding!
