The same is true of middle-class schools in the United States. Teachers still control students in order to find jobs and go to college. However, the teachers in these schools have good personalities, and they can abide by the system themselves, at least they will not delay classes. Usually, doctors and lawyers are the favorites of the middle class in the field of education.
Doctors and lawyers need long-term study and training, and they have special skills. You can only work if you get a qualification certificate, and you also have your own professional standards. These people are upper-middle class, earning a lot of money, and have good plans for their lives and careers.
Education of the ordinary working class
Ordinary working-class schools emphasize compliance with rules and procedures. The whole teaching is full of rote mechanical procedures, and there is almost no chance to make choices and decisions. Teachers teach everything by instilling rules in students, even solving math problems.
These rules usually include several steps, and students must remember each step. Teachers often look at whether your final result is right, but whether you have memorized the steps!
