     At present, in many American cities especially, many teachers in the public schools say they are underpaid.

They point to jobs such as secretary or truck driver, which often pay more to start than that of a teacher. In

many other fields, such as law, medicine, computer science, a beginning worker may make more than a teacher

who has taught for several years.

     Teaching has never been a profession that attracted people interested in high salaries. It is by history a

profession that has provided rewards in addition to money-the satisfaction of sharing knowledge, of influencing

others, of guiding young people. But in the past several years, there are more difficulties in teaching, for many,

than there are rewards.

     Unruly students, especially in big cities, large classes and a lack of support from the public in terms of money

and understanding have led many public school teachers to leave the profession.

     As a result, many of the best students, who would have chosen teaching as their life career in the past, are

going into other fields.

     Another reason for this change in teacher candidates is the changing status of women in the United States.

Until the late 1960s and 1970s, one of the most popular choices for women was teaching. But as other

professions, such as law and medicine opened up to women, women stopped pouring into teacher training

programs. Thus, a major pool of excellent candidates for the teaching profession dwindled.

     Bit by bit government officials and others realized that the status of the teacher had suffered. They talked

about change. But the change in a vast society like the United States is not easy. People's attitudes have formed

over many years, and sometimes change takes many years.
