IMHO a better approach to discussing life choices is to start with the students. The students are the customers.

In competitive team sports. The coach is the customer and the students are the product.
This brings us back to active vs passive voice. One needs to identify who the primary actor is. Schools should organize things so that the student is the primary actor in most situations.
