How Do Schools Function as a Means of Social Reproduction

How do schools function as a means of social reproduction?

A) Schools train, reward, and sort students into social classes and for future roles in a "justified" capitalist society.
B) Schools mirror the workplace in such a way that students are acclimated for capitalism the moment they graduate.
C) Students are managed, leveraged into the roles that make them useful. Students who refuse to be useful are leveraged out. In this way, inequalities are both established and perpetuated.
D) The schools harness the creative power and intelligence of their students and channel them to serve the interest of the oppressor.
