This has nothing to do with fairness, the schools, the teachers, nor anything else they throw into the argument.

Most of the "bad" schools get the same (or even more) amount of funding, resources, coursework/material, as the "good" schools.

The difference that separates the two categories are the students (and their parents).

Charter schools simply don't have to put up with the same destructive students - and are able to create a productive environment for learning for the constructive students.

The problem is they tend to also not follow the NAACP approved racial demographics/splits.
