One of the causes for this is that teaching is not a lucrative job, and earnings in teaching are much lower than many others jobs, as a result, fewer and fewer graduated people want to be a teacher as it cannot meet their basic needs. For example, graduated people can earn twice as much if they work in marketing and advertisement. In addition, they have a large range of duties and responsibilities without appreciation or respect, because some pupils do not have the same respect for teachers as in the past, or they may disobey the teachers.
