Oppression can be defined as the exercise of authority or power in a burdensome, cruel, or unjust manner. In the case of education, a teacher should not be looked upon as a tyrant or person of extreme power or authority. With the Banking Concept of Education, students are basically powerless and are faced with a teacher or in this case, emotionless character of knowledge who's responsible for forcing information into students brains for the purpose of regurgitating on command. By doing so, students are deprived of the chance to look and analyze information they are given in detail and are denied the opportunity to apply the information into real life situations and seeing how the information functions within society.
A strong enemy of the Banking System of Education is Paolo Freire, who fights for the idea problem-posing education in order to ignite students critical thinking. Freire states, "Whereas banking education anesthetizes and inhibits creative power, problem-posing education involves a constant unveiling of reality. The former attempts to maintain the submersion of consciousness; the latter strives for the emergence of consciousness and critical intervention in reality."
You previously said, "students are basically powerless" which in some cases could prove true. However, this has nothing to do with the banking concept, instead, it has to do with the teacher and the way they choose to do their job. Without the banking concept of education, students will be subject to favoritism and special treatment which, in some cases could be beneficial. But, this will overall cause inequality in the classrooms and causes oppression to occur for the students who perhaps do not receive equal treatment from their teachers. Hirsch once stated, "It is the background information, stored in their minds, that enables them to take up a newspaper and read it with an adequate level of comprehension, getting the point, grasping the implications..."(1.3) This explains that the teachers simply provide a series of information that every person should know. The banking concept is the only way to achieve full equality in schools and is in fact not oppressive because the teachers are simply providing things that every person should know.
