What is the point of Public School? As I understand it, it is put in place to ensure that all children have opportunities, rather than only being available to the rich. 

Today I was talking to a woman with a grandchild in school who was talking about how her child would not be able to get a good grade in her "excellence" class. This class is one where you go out after school, and get lessons in music, horse-riding, painting, or math. Her family can't afford to put her children through a private art class, therefore her child will fail "excellence" class.

So suddenly, I have to ask again... what is the point to public education?
